The single limb squat comes in a lot of variations regarding body position, but in this video we are going to focus on depth.
Building dynamic muscle function must incorporate training EVERY type of muscle action, including eccentrics. The lowering phase towards the ground in all squatting motions requires eccentric muscle strength. The body is essentially a system of cranes (muscles) with multiple integrated pulleys (joints/tendons/ligaments) that can slowly lower the weight of the body. What's more important is you need eccentric strength prior to dynamic concentric strength, you must learn to absorb before you can produce. If your performance of the task decreases as you increase depth, you're not ready to progress! Remember to always promote quality over quantity!
