Rethinking Barefoot Shoes: Why They Might Not Be Right for You

Barefoot shoes have become a go-to choice for people wanting to “fix” their feet or move more naturally. They’re light, flexible, and promote toe splay—all great things in theory. But when you look at how most of us actually live and move today, barefoot shoes may not be the solution they’re marketed to be.

Barefoot Shoes Were Designed for a Different Environment

These shoes are inspired by the way we used to move: walking on grass, dirt, sand, and other uneven terrain. Environments that challenged the foot to adapt, respond, and build strength.

But that’s not how we move now. Most people walk on flat, hard surfaces—sidewalks, tile, gym floors, concrete. Take away all the structure and cushioning, and you’re now asking your foot to do more work without the natural variability it needs to do it well.

This mismatch often leads to increased strain on the feet, knees, and hips.

Why Feeling the Ground Isn’t Always Enough

A common argument for barefoot shoes is “feel the ground.” But without something to push into, that sensation can become meaningless—or worse, problematic.

Your foot is meant to roll in, absorb force, and push off. When a shoe doesn’t give you any structure to push into, your body can’t organize movement efficiently. That can lead to things like:

  • Flat, collapsed arches

  • Overworking small foot muscles

  • Tight calves and ankles

  • Poor balance and control during walking or training

What’s Good About Barefoot Shoes (And What’s Missing)

To be clear, barefoot shoes do some things well:

  • Wide toe boxes let your toes spread naturally

  • Thin soles improve sensory feedback

  • Zero-drop heels encourage a more upright posture

But on consistently flat, hard ground, these same features can become stressors. They remove too much structure—leaving your body with no support to work with. It’s not that they’re bad, but they aren’t ideal for most people living modern, indoor lives.

What to Look for in a Shoe That Supports You

Instead of going fully minimal, consider footwear that strikes a better balance between freedom and structure. A well-designed shoe should:

✅ Have a Firm Heel

Helps with stability during walking and lifting by anchoring the back of your foot.

✅ Be Flexible at the Toes

Let your big toe extend so you can push off properly during movement.

✅ Offer Moderate Arch Support

Just enough to guide motion—not restrict it. Especially important for those with flat feet or instability.

✅ Include a Slight Heel Drop (4–8 mm)

This small lift can take pressure off the calves and improve overall gait mechanics.

✅ Provide Cushion for Flat Surfaces

Some padding helps absorb repetitive impact from walking and training on hard floors all day.

Note: I’m talking here about everyday shoes—the ones you wear to walk, run errands, train, or do light accessory work. For heavy, bilateral lifts like deadlifts, I’ll still lift barefoot or in minimalist shoes. The shoes I recommend above can be versatile enough to train in, but not ideal for max-effort strength work. It all depends on the context, and at the end of the day what works best for you.

The Bottom Line

Barefoot shoes can be useful—in the right environment, and for the right person. But for most people training, walking, and living on hard, flat surfaces, they often cause more problems than they solve.

A good shoe doesn’t just let you feel the ground—it gives you something to push into. It should support how your body moves and make your life easier, not harder.

Why You Should Focus on Building an Aerobic Base Before High-Intensity Training

If you’re looking to improve your endurance and overall fitness, you might think that going all out with high-intensity workouts is the fastest way to get there. However, when it comes to long-term progress—especially for those training for demanding physical tests like the firefighter physical exam—building a strong aerobic base first is crucial.

What Is an Aerobic Base?

Your aerobic base refers to the foundation of your cardiovascular system’s ability to efficiently use oxygen to generate energy. This system primarily relies on oxidative phosphorylation, a process that allows your body to sustain activity over long durations with minimal fatigue. Training at the right intensities helps improve mitochondrial density, capillary growth, and fat oxidation—key factors in enhancing endurance performance.

Why High-Intensity Training Can Hinder Aerobic Development

Many people assume that intense training leads to faster results, but high-intensity conditioning can actually interfere with aerobic adaptations. Here’s why:

  1. Increased Anaerobic Dependence – When you train at high intensities, your body shifts toward anaerobic energy systems (like glycolysis), which produce energy quickly but generate metabolic byproducts like lactate. While your body can handle short bursts of anaerobic work, it’s not an efficient long-term strategy for endurance development.

  2. Recovery Demands and Fatigue – High-intensity sessions place significant stress on your muscles and central nervous system, requiring longer recovery times. If done too frequently, they can lead to excessive fatigue and overuse injuries, ultimately stalling progress.

  3. Limited Oxygen Utilization Training – Training at lower intensities allows your body to maximize oxygen delivery and utilization, leading to improvements in aerobic capacity (VO2 max), capillary density, and mitochondrial function. These adaptations are essential for sustained endurance.

  4. Interference with Adaptations – High-intensity workouts primarily target fast-twitch muscle fibers, while aerobic base training focuses on slow-twitch fibers, which are more efficient at using oxygen for fuel. Overemphasizing high-intensity work too soon can reduce the effectiveness of these adaptations.

The Right Approach: Base Building First

For the first 8-12 weeks of a structured training program, focusing on low to moderate-intensity conditioning is crucial. This means training in specific heart rate zones (usually 60-75% of max heart rate) to optimize oxygen utilization. The goal is to improve endurance while keeping fatigue and injury risk low.

Once a strong aerobic foundation is built, higher-intensity sessions can be strategically incorporated to enhance performance without compromising recovery or long-term progress.

Key Takeaways

  • Building an aerobic base improves endurance, recovery, and efficiency.

  • High-intensity training too early can lead to fatigue, increased injury risk, and limited aerobic gains.

  • A structured plan prioritizing aerobic development first leads to better long-term performance.

If you’re serious about improving your cardiovascular fitness, whether for general health or a specific goal like passing a physical test, patience and consistency with aerobic base training will set you up for success.

Why You Should Rethink How You Row: The Truth About Shoulder Blade Cues

You’ve probably heard it before:
"Pull your shoulder blades together.”
It’s a cue that’s been passed around gyms and group classes for years.

But here’s the truth: overemphasizing scapular retraction during pulling exercises — like rows and pulldowns — can limit shoulder health, breathing mechanics, and strength development.

If you care about moving better, not just lifting more, it's time to rethink how you row.

1. Over-Retraction Limits Ribcage Expansion

When you cue scapular retraction too forcefully during a row or pulldown, you compress your upper back and limit ribcage movement. This restricts natural thoracic mobility and can impact your ability to breathe and move efficiently under load.

👉 See more on mobility training

2. It Disrupts Scapulohumeral Rhythm

The scapula and humerus are designed to move together in a fluid, coordinated rhythm. Forcing the shoulder blades into retraction first interrupts that sequence. This increases joint stress and decreases the efficiency of your movement — especially in horizontal pulling patterns.

3. You Miss Out on Serratus Activation and Posterior Expansion

When you stop at scapular retraction, you lose out on the benefits of a full reach — which promotes serratus anterior engagement and helps open up the back of the ribcage. This reach improves shoulder function and breathing capacity, particularly for clients struggling with postural restrictions or breathing mechanics.

4. It Reinforces Compensatory Movement Patterns

Cues like "pinch your shoulder blades" often drive people into extension-based strategies — excessive lumbar arching, rib flaring, and overuse of the lats and lower back.

Instead, focus on staying stacked: ribs over pelvis, neutral spine, and movement that flows from a stable foundation.

👉 Learn more about injury prevention strategies

What Proper Row and Pulldown Mechanics Look Like

  • Elbow leads the movement — not the scapula

  • Scapula glides naturally with the arm

  • Reach at the start and end for full range

  • Spine stays neutral, not overextended

  • Breathing stays consistent throughout the set

Better Cues to Use Instead

  • “Elbow to back pocket.”

  • “Let the shoulder blade follow the arm.”

  • “Reach at the end — don’t stop at the shoulder blade.”

  • “Stack your ribs over your hips.”

Stop Balancing on a BOSU Ball: What the Research Actually Says About Unstable Surface Training

Let’s get one thing straight: balancing on a BOSU ball is not a badge of athleticism. Yet, I constantly see people in the gym doing squats or biceps curls on unstable surfaces thinking they're improving ankle strength, core function, or stability.

It’s a well-intentioned but misguided strategy. So, what does the research actually say about unstable surface training?

What Is Unstable Surface Training (UST) Really Training?

Unstable surface training—using tools like BOSU balls, wobble boards, or foam pads—adds instability to exercises, forcing the body to work harder to stay balanced. This does a few things:

  • Increases neuromuscular coordination demands

  • Engages the vestibular system and visual feedback

  • Activates postural muscles through reflexive adjustments

  • Requires greater core and small muscle engagement

Sounds like a win, right?

Not so fast.

The Ankle Stability Myth

Ankle sprains make up about one-third of all sports injuries, and the recurrence rate is shockingly high—up to 70%. A lot of this is due to poor proprioception—the body’s ability to sense joint position and movement.

So people assume that training on unstable surfaces improves proprioception and ankle stability.

But here's the problem: it doesn’t.

One study looked directly at proprioceptive training and found that exercises performed on unstable surfaces did not effectively improve proprioception or joint position sense. In other words, wobbling doesn’t equal proprioceptive adaptation (Wright & Arnold, 2012).

Strength Loss on Unstable Surfaces

Not only are you not improving ankle function—you might be compromising your strength, too.

A 2021 study found that grip strength and overall power output were significantly reduced when resistance exercises were performed on unstable surfaces (Zemková et al., 2021). That’s because your body’s focused on not falling over rather than producing force.

Another systematic review echoed this, concluding that unstable surface strength training has limited transfer to strength and power in stable, real-world conditions (Behm et al., 2015).

Translation: You’re getting worse at lifting and still not preventing that ankle sprain.

So What Should You Do for Ankle Stability?

There’s solid evidence that certain proprioceptive and strength training strategies actually reduce ankle sprain recurrence:

Controlled Strength Training

  • Calf raises (bent and straight knee)

  • Tibialis raises, toe walks

  • Split stance and single-leg exercises with tempo

Sensory-Motor Work

  • Eyes-closed balance drills on a firm surface

  • Controlled single-leg deceleration (hop and stick)

  • Multidirectional landing mechanics

Reactive & Perturbation Training

  • External taps or light band perturbations while holding position

  • Partner drills mimicking sport-specific movement

These strategies are rooted in actual performance and rehabilitation research (Schiftan et al., 2015), and more importantly—they help you move better, get stronger, and build confidence after injury.

Final Thoughts

Unstable surface training isn’t evil—it has its time and place, especially in rehab or return-to-play. But for most people chasing strength, resilience, or better ankle stability, it’s a poor substitute for well-designed, progressive training.

So unless your goal is to join Cirque du Soleil, maybe leave the BOSU ball alone.

Train smart. Get strong. Train. Play. Repeat.

The Science of Sleep: How to Optimize Recovery and Performance

Sleep is one of the most critical, yet often overlooked, components of overall health and athletic performance. High-quality sleep is essential for physical recovery, cognitive function, and long-term well-being. Whether you're an athlete striving for peak performance or someone simply looking to improve daily function, optimizing sleep should be a top priority.

How many hours should you sleep a night?

Research generally suggests that most adults should aim for 7 to 9 hours of sleep per night to maintain overall health, with individual needs varying based on factors like age, lifestyle, and genetics. For athletes, the recommendations can differ slightly due to the physical demands placed on their bodies.

  • General population:

    • Adults: 7–9 hours per night

    • Teens: 8–10 hours per night

    • Children: 9–11 hours per night

  • Athletes:
    Athletes often require more sleep for recovery, muscle repair, and optimal performance, with some research suggesting that 8–10 hours per night may be ideal, especially for those who train intensely or frequently

The Importance of Sleep for Health and Performance

Physical Recovery and Performance

Sleep is when the body undergoes the majority of its repair and recovery processes. During deep sleep (slow-wave sleep), the body increases the release of human growth hormone (HGH), which is crucial for muscle repair, bone growth, and tissue regeneration (Leeder et al., 2012). Additionally, inadequate sleep can lead to decreased glycogen storage, reduced muscle protein synthesis, and impaired immune function, all of which can negatively impact athletic performance (Halson, 2014).

For athletes, studies have shown that sleep deprivation leads to reduced reaction time, impaired motor function, decreased endurance, and an increased risk of injury (Fullagar et al., 2015). A study on basketball players found that increasing sleep duration improved sprint times, shooting accuracy, and overall performance (Mah et al., 2011).

Cognitive Function and Decision-Making

Cognitive function is just as critical as physical performance, especially in sports that require strategic thinking, quick reactions, and split-second decision-making. Poor sleep has been linked to impaired memory, decreased attention span, and slower reaction times (Walker, 2017). For athletes, this means a diminished ability to anticipate plays, make precise movements, and adapt to in-game situations.

Hormonal Balance and Mental Health

Sleep plays a vital role in regulating hormones, including cortisol (the stress hormone) and testosterone. Sleep deprivation increases cortisol levels, which can lead to elevated stress, impaired recovery, and increased fat storage (Samuels, 2008). At the same time, sleep is necessary for optimal testosterone production, which is important for muscle growth, strength, and recovery.

Additionally, inadequate sleep is linked to mood disturbances, increased risk of depression and anxiety, and overall reduced well-being. A well-rested athlete is not only physically prepared but also mentally sharper and more resilient.


How to Optimize Sleep for Better Recovery and Performance

1. Maintain a Consistent Sleep Schedule

Going to bed and waking up at the same time every day helps regulate your body’s internal clock (circadian rhythm), leading to better sleep quality. Inconsistent sleep patterns can disrupt recovery and performance (Dijk & Archer, 2009).

2. Create an Ideal Sleep Environment

  • Keep it Cool: The optimal room temperature for sleep is between 16-19°C (60-67°F). I personally take this to the next level by opening all bedroom windows before bed to maximize cool airflow

  • Eliminate Light: Darkness signals the brain to produce melatonin, a hormone that promotes sleep. Use blackout curtains or an eye mask

  • Reduce Noise: White noise machines or earplugs can help block disruptive sounds. I sleep with an air purifier on, which not only improves air quality but also provides soothing background noise

  • Incorporate Plants: Snake plants are a great addition to the bedroom as they improve air quality by filtering toxins and increasing oxygen levels, which can promote better sleep

3. Minimize Screen Time and Optimize Lighting

Blue light from phones, tablets, and TVs suppresses melatonin production and interferes with sleep quality. Try to avoid screens at least 60 minutes before bedtime or use blue light filters (Chang et al., 2015).

One of my biggest nighttime game-changers has been switching all bedroom lights to red light bulbs. Red light has been shown to have minimal impact on melatonin production, making it an ideal choice for nighttime lighting. I even installed red puck lights in the bathroom to prevent harsh light exposure when brushing my teeth or washing my face at night.

A dimly lit bedroom bathed in a warm red glow from red light bulbs, creating a calming atmosphere ideal for restful sleep.

4. Prioritize a Pre-Sleep Routine

Establishing a wind-down routine can signal to your body that it’s time for rest. Consider:

  • Reading a book for 30-60 minutes before bed (this has been a game-changer for me)

  • Practicing deep breathing or meditation

  • Gentle stretching or mobility work

5. Manage Caffeine and Alcohol Intake

Caffeine has a half-life of 5-6 hours, meaning it can stay in your system for a long time. Avoid consuming caffeine at least 6 hours before bed. While alcohol might make you feel sleepy, it disrupts REM sleep and overall sleep quality (Roehrs & Roth, 2001).

6. Try Magnesium Spray for Relaxation

Another tip worth trying is applying magnesium spray to the bottoms of your feet before bed. Magnesium plays a key role in muscle relaxation, stress reduction, and sleep regulation. Some people find it helps improve sleep onset and quality, making it a great addition to your nighttime routine.

7. Use Sleep Tracking to Optimize Habits

Wearable technology and sleep tracking apps can provide insights into sleep patterns and help identify areas for improvement. Tracking heart rate variability (HRV) and sleep duration can help athletes understand their recovery needs better (Walsh et al., 2021).


Final Thoughts

Sleep is a fundamental pillar of health and performance. It impacts everything from physical recovery and injury risk to cognitive function and hormonal balance. Prioritizing high-quality sleep through consistent habits, proper sleep hygiene, and lifestyle adjustments will enhance athletic performance, mental clarity, and long-term health.

Investing in better sleep isn’t just about feeling well-rested—it’s about optimizing your body’s ability to perform and recover at its highest potential. Train hard, recover smart, and sleep well.

Why Women Need a Different Approach to Post-Training Nutrition and Fasting

When it comes to post-training nutrition and fasting, men and women are not the same. While much of the mainstream advice on nutrition and recovery is based on research conducted on men, emerging studies—led by experts like Dr. Stacy Sims—highlight the critical differences in how women should approach fueling and recovery. From the shorter post-training refueling window to the negative effects of fasted training, women need a tailored approach to optimize performance and long-term health.

Post-Training Nutrition: Why Women Need to Refuel Sooner

After training, the body enters a recovery phase where it repairs muscle tissue, replenishes glycogen stores, and shifts from a catabolic (breakdown) state to an anabolic (building) state. The timing of this recovery process differs significantly between men and women.

  • Men have a longer window to refuel. Research suggests that men can maintain an elevated metabolic rate and glycogen resynthesis for up to three hours post-training. This gives them more flexibility in delaying post-workout meals.

  • Women need to refuel within 30 to 90 minutes. Women’s metabolisms return to baseline much faster—typically within 60 to 90 minutes—meaning that delaying nutrition can hinder muscle repair and recovery.

Dr. Sims recommends that women prioritize at least 35 grams of high-quality protein within 45 minutes of finishing a training session. Pairing protein with carbohydrates helps replenish glycogen stores and prevent excessive muscle breakdown.

The Problem with Fasted Training for Women

Fasted training—exercising on an empty stomach—is often promoted as a tool for fat loss and metabolic efficiency. While this approach may work for some men, the physiological response in women is quite different, often leading to more harm than good.

1. Hormonal Disruptions

Women’s bodies are highly sensitive to energy availability. Training in a fasted state can disrupt key hormones like estrogen, progesterone, and cortisol, leading to negative effects such as irregular menstrual cycles, decreased thyroid function, and metabolic slowdowns.

2. Increased Stress Response

Morning cortisol levels are naturally high, and exercising without food further elevates stress hormones. This can lead to:

  • Increased muscle breakdown

  • Higher levels of fatigue

  • Poor recovery over time

3. Impaired Performance and Recovery

Without adequate fuel, women often struggle to reach high training intensities. This means workouts may be less effective, leading to slower progress in strength and endurance. Additionally, prolonged fasted training can contribute to low energy availability (LEA), which has been linked to increased injury risk, poor immune function, and chronic fatigue.

What Women Should Do Instead

Instead of training fasted, Dr. Sims suggests women eat a small pre-training snack containing protein and carbohydrates, such as:

  • A banana with a small amount of nut butter

  • Greek yogurt with berries

  • A protein shake with half a scoop of whey and some oats

Then, follow up with a proper post-training meal that includes a balance of protein, carbohydrates, and healthy fats to optimize recovery.

Final Thoughts

The takeaway? Women need to refuel sooner post-training and avoid fasted exercise to support optimal hormone function, performance, and long-term health. While men may have a more extended recovery window and can tolerate fasting with fewer consequences, women benefit from a more consistent intake of nutrients throughout the day.

By adjusting nutrition strategies to align with female physiology, women can maximize their training results, recover more efficiently, and sustain long-term health and performance.
