The term “evidence-based training” gets thrown around a lot. But what actually makes a coach evidence-based? Reading studies? Having a kinesiology degree? Posting PubMed screenshots on Instagram?

True evidence-based practice goes far beyond quoting research. It is about combining the best available evidence with real-world experience and applying it to the needs of the person in front of you. Too often, that third piece gets ignored.

Foundations First: Coaching Is a Skill, Not a Certificate

You cannot replace lived experience and movement literacy with citations. A coach should know how to move well, demonstrate patterns clearly, and teach with purpose. That takes time under the bar, time on the floor, and years of refining their craft.

You can have a kinesiology degree and still not know how to coach a hinge or assess a client’s squat depth.

At Avos Strength, every junior coach goes through a structured three-month mentorship. They do not just learn protocols. They shadow real sessions, practice cueing, and refine how they coach. Because knowing the “why” is not enough. You also need to know how to deliver the “how.”

Shadowing Matters: Who You Learn From Shapes How You Coach

There is nothing wrong with being new. But good coaches are forged through time, mentorship, and reps.

I shadowed for years without getting paid. Why? Because that is how you build the craft.

Watching seasoned coaches, asking questions, getting feedback, and coaching real people is where you truly grow.

If you are looking to work with a coach, ask:

Who did they learn from?
Do they train themselves?
Do they continue to shadow and learn?

Education without application is just theory.

Yes, the Research Matters. But Know What It Really Says

Let’s be clear. The research is valuable. But it must be understood in context.

Take hypertrophy. For years, people believed you had to train in the 6 to 12 rep range to build muscle. But newer research shows you can build muscle at a wide variety of rep ranges, as long as effort and volume are managed properly.

That means the “best” rep range is the one that fits the person’s goals, experience, and recovery capacity. That is where coaching comes in.

The Bottom Line: Coaching Comes First

Evidence-based is not a title. It is a practice. And that practice only works when you have coaches who understand movement, know how to teach it, and apply research with intention.

If you are a client, look for a coach who:

Moves well and teaches movement clearly
Understands the research but does not hide behind it
Has put in time shadowing and learning from experienced professionals
Tailors training to your needs, not just to a textbook

If you are a coach, do the real work. Don’t just quote studies. Learn to coach.

Why Leucine Matters Most for Muscle Growth and Recovery

Let’s talk about protein. More specifically, let’s talk about leucine.

Whether you're working to build strength, improve endurance, or maintain lean muscle as you age, your ability to recover and grow depends on one key trigger: muscle protein synthesis. And one amino acid plays the leading role in that process.

What Is Leucine and Why Does It Matter?

Leucine is one of the essential branched-chain amino acids (BCAAs). It acts as the “on switch” for muscle repair by activating a molecular pathway called mTOR, which tells your body to start rebuilding muscle tissue after training.

Without enough leucine, even a high-protein meal may not fully trigger muscle protein synthesis. This is why protein quality and amino acid composition matter just as much as hitting your total protein intake.

Why It’s Especially Important for Women

Women tend to have lower baseline rates of muscle protein synthesis compared to men, partly due to hormonal differences. For example, muscle breakdown increases during the luteal phase of the menstrual cycle, just before your period.

This is one area where Dr. Stacy Sims' work is helpful. In her book ROAR, she highlights the importance of choosing leucine-rich protein sources, especially after strength training or during high-hormone phases when recovery can be compromised.

The research supports this. For both performance and recovery, women benefit from being more deliberate with post-training protein intake.

What to aim for: At least 2.5 grams of leucine in your post-training meal or shake. This is typically the minimum needed to fully activate muscle repair pathways.

How Much Protein Do You Actually Need?

For active individuals, the research-supported recommendation is about 1.8 to 2.2 grams of protein per kilogram of body weight per day.

That protein should be spaced throughout the day across three to five meals, with roughly 20 to 40 grams of protein per meal depending on your size, goals, and training demands.

For both men and women, leucine still matters. If you don’t hit the leucine threshold in a meal, your body may not initiate the repair process efficiently, even if you meet your total daily intake.

What Plant-Based Athletes Need to Know

If you follow a plant-based or vegan diet, this is something to pay attention to. Many common plant-based protein sources like pea, rice, and hemp contain less leucine per serving than whey or other animal-based proteins.

Some vegan protein powders contain only 1 to 1.5 grams of leucine per serving. That is not enough to reach the 2.5-gram mark that research suggests is needed to trigger muscle protein synthesis effectively.

If your protein label doesn’t list leucine content, check the brand’s website or reach out to the company directly. You may need to supplement with isolated leucine powder or choose a blend that brings you closer to that threshold.

Simple Strategies That Work

If you are not vegan, choose a high-quality whey isolate after training. Most servings contain around 2.7 grams of leucine.
If you are vegan, look for blends that list leucine content and get close to 2.5 grams, or add free-form leucine to your post-workout shake.
Do not rely on BCAAs alone. Always aim for a complete protein source after lifting or intense training.
For women, be especially strategic about recovery nutrition during the luteal phase, when muscle breakdown is elevated.

The Bottom Line

Leucine is not just another buzzword. It is one of the most important amino acids for recovery and muscle growth.

Whether you eat animal protein, plant-based protein, or a combination of both, what matters most is that you are getting enough leucine to support the work you are putting in at the gym or on the field.

If you want to build muscle, maintain strength as you age, or support your training with purpose, start by paying attention to your post-workout protein. Total intake matters, but leucine matters even more.

Train. Play. Repeat.
