## What is Muscle & Motion?

Build strength with guided workout plans, gym routines, and in-depth biomechanics. Muscle & Motion brings training to life with 3D visuals that show how your body moves.

The Strength Training app is powered by a team of physiotherapists, movement experts, and professional animators. We turn your device into a visual strength-training lab and show you exactly which muscle structures are working, so you can understand the anatomy and  biomechanics of the exercise, and train smarter while reducing injury risk.

Made for personal trainers, strength coaches, therapists, students, and dedicated lifters, this app connects what you feel in the gym with what’s really happening in the body.

Designed for visual learners
If you learn best by seeing, this app is made for you.

Why trainers, coaches & students love it


- Makes complex anatomy easy to understand through clear 3D animations

- Shows exactly which muscles and joints are involved in each exercise

- Reveals common mistakes so you can coach better form

- Explains concepts far better than static images or textbooks

Backed by thousands of 5-star ratings and trusted by movement professionals worldwide.

Instead of static diagrams, you get animated 3D views of real lifts: muscles slide, shorten and lengthen as the movement happens, making it much easier to remember which structures are doing what, and why it matters

Key features:

• Interactive 3D Anatomy Model
Rotate, zoom, and explore every muscle, joint, and bone for a deeper understanding of human movement.

• Access to 3D Exercise Anatomy Library (1,200+ exercises, updated weekly)
Comprehensive library of science-based exercise videos, each with full anatomical analysis and common mistakes to avoid. See prime movers, synergists, stabilizers and antagonists highlighted with clear color-coding, and learn how to target or de-emphasize specific muscles by changing stance, range, or grip.

• Educational Videos 
Discover a range of videos designed to make learning anatomy easy and engaging. From core fundamentals to advanced mechanics.

• Workout Plans
Create & assign customized workouts

### 5/5 — Best ever app

*2026-08-11*

Excellent app to learn body mechanics, best for gain knowledge

### 4/5 — Bien mais un peu trop chère

*2026-08-06*

Cette appli est vraiment top mais elle reste assez chère. J’aurais aimé avoir plusieurs niveaux d’offres. Mon usage dans un premier temps se limiterait à la consultation des planches anatomiques et des mouvements. N’étant pas coach, la partie programme ne m’intéresse pas plus que ça.

### 4/5 — Great knowledge builder

*2026-08-04, version 3.5.3*

I downloaded this app as the sister to an anatomy app I’m purchasing. I have enjoyed the experience of the very few free sections. I may purchase this app as well.

### 5/5 — Very beneficial

*2026-08-03, version 3.5.3*

Explains what to do, but importantly, not what to do in terms of lifting mechanics, as well as explaining what muscles, tendons and ligaments are involved with each movement.

### 5/5 — Incredibly Helpful

*2026-08-02, version 3.5.3*

I’m a very visual learner and need better explanations to really understand, and books can only help but so much. 

This app helps boost my confidence with the interactive features, detailed exercise explanations for proper form, anatomy functions and you can build your own workouts!! 

I purchased the yearly plan at 40% off and it’s an incredible value!!

### 5/5 — Excellent app

*2026-07-30, version 3.5.3*

I love how much you can learn in this app and how well it is explained. The visuals are great

### 5/5 — Great app

*2026-07-24, version 3.5.3*

Just downloaded it and can tell it’s going to be an awesome app for personal trainers

### 5/5 — Great app

*2026-07-23, version 3.5.3*

I got everything I wanted from this app and even more!

### 5/5 — Love this app

*2026-07-21, version 3.5.3*

Great app ,
Using to help out with personal training

### 5/5 — Love it

*2026-07-13, version 3.5.2*
