However, they also help to protect bones from being damaged, and our fragile tendons, joints and ligaments from tearing or suffering painful injuries. Its an absolutely crucial component of any kind of action, and works alongside the antagonist muscle to create contractions and extensions. The gluteus Maximus is heavily activated during the concentric phase of the squat therefore it is important to have great range of movement to for greater muscle fibre recruitment in gluteal muscles. One of the functions of that muscle will be to aid or cause movement around that joint. This will happen because there will be longer distance to travel to achieve full extension of the knee and hip.

The subjects performed DJs with two drop heights (0.2 and 0.4 m) and three different efforts (maximal rebound height, 50% effort of maximal rebound height and landing without rebound). Secondary muscles that are worked when squatting are calves. Slight pronation is allowed but the individual should be able to perform the movement pattern by primarily flexing at the ankle versus complete collapse of the arch. The key here is that youre working one muscle group while allowing the opposing one to recover.

This typically requires at least 15-20 of ankle dorsiflexion and 120 of hip flexion (Greene, 1994). As weve previously mentioned, the bicep curl goes through two main motions - the lift, and the subsequent relaxation. As one muscle contracts, the other relaxes. Without this opposing force, you seriously risk damaging your muscles, joints, and overall skeletal health, especially with movements like bicep curls or deadlifts, which can often be coupled with significant weight in addition to the muscular exertion.
