Bodyweight Squat

Muscles worked

The prime movers are the quadriceps across the front of the thigh, which straighten the knee and, just as importantly, control it on the way back down.

Because more than one joint is moving, the work does not stay in one place: the glutes finish hip extension; the hamstrings assist hip extension and slow the knee down.

How this movement works

The working muscles shorten as they drive the load away from you, and more than one joint changes angle to do it. Load spreads down a chain instead of sitting on one muscle, which is why a compound push handles more weight than any single-joint alternative — and why joint position, not the muscle, is usually what fails first.

It is filed under strength: produce force against resistance for a countable number of repetitions, and progress the resistance over time.

What you need

No equipment at all. The resistance is your own bodyweight, so you progress by changing leverage, range or tempo rather than by adding plates — and you can do it anywhere.

Difficulty

Listed at beginner level: the pattern is simple enough to pick up without coaching, and a position that goes wrong mid-set is obvious enough to correct on the next repetition.
