THE 16 BIOMECHANICAL
FACTORS EXPLAINED
Understand how SmartTraining365 evaluates every exercise so you can train with precision, safety, and maximum efficiency.
This lesson is the foundation of the
SmartTraining365 methodology
You’ll learn the 16 biomechanical factors that determine whether an exercise is efficient, safe, productive,
or a waste of time — and how these principles directly influence hypertrophy, strength, and long-term joint health.
If you truly want to understand exercise selection on a scientific level, start here.

This training reveals:
✔ how each factor impacts muscle loading
✔ how to evaluate ANY exercise
✔ how to avoid wasted effort, joint strain, and poor mechanics
✔ why BRIG20 exercises outperform traditional lifts
✔ and how to make precise decisions for your goals

What You Will Learn
How anatomical motion determines which muscles are truly being loaded
Why full range of motion outperforms partials (and when partials make sense)
How reciprocal inhibition compromises many compound exercises
The difference between active and passive insufficiency
How joint positions influence muscle strength and stretch
Why independent loading improves coordination and hypertrophy
How to identify moment-arm advantages and disadvantages
The physics behind early-phase loading and why it matters
How stability affects force production and safety
How to analyze resistance direction, torque, and limb trajectory
And much more — all applied to real exercises
Who Is This For
If you’ve ever questioned traditional training methods — this will give you the answers.
Why These 16 Factors Matter
Once you understand these factors, you can:
Identify the safest and most productive version of any exercise
Know instantly whether a movement is efficient or flawed
Train harder and safer at the same time
Select exercises that match your goals (hypertrophy, strength, mobility, rehab)
Avoid exercises that waste energy or overload the joints
Build muscle faster, with less guesswork, and no unnecessary risk
This is the knowledge that separates training from exercising.

Explore the next two foundational SmartTraining365 teachings:
• BRIG20 vs Compound — For Hypertrophy
Understand why compound lifts are not always the most efficient choice, and how
BRIG20 exercises maximize muscle loading.
• Partials vs Full Range of Motion — Based on Biomechanical Principles
Learn when partial reps make sense, when they compromise your
training, and how physics determines the truth.

Understand how SmartTraining365 evaluates compound vs BRIG20 exercises and learn when each one should be used depending on your goal.

A biomechanics-based guide to partial reps exercise selection, lengthened vs shortened partials, and where partials fit inside BRIG20 and goal-specific programming.
