While there are numerous benefits to deadlifts, its vitally important to understand the fundamentals, and how the necessary antagonist and agonist muscle movements form the basis of all the exercises you complete. In these instances, flexibility exercises for the calves and possibly joint mobilization for the ankle may be required to regain 15-20 of ankle dorsiflexion. While the agonist contracts causing the movement to occur, the antagonist typically relaxes so as not to impede the agonist, as seen in the image above. Interested? When the leg is lifted away from the midline the gluteus medius fibers contract. Hamstrings lengthen during the eccentric phase (negative movement) to flex the knee. We use these muscles every single day, and largely without realising that we do, as they're used in many everyday tasks. The final phase of the squat is the concentric contraction where quadriceps muscles, contract/shorten and opposing muscles (hip flexors) lengthen. These muscles move in the opposite direction to the agonist muscles, and offset the force these muscles exert so that we dont damage our fragile joints. Subtalar joint is going to be involved when athletes are going to have poor technique and one of the sides of the feet are going to come off the ground creating inversion if the inside of the of the foot is coming off the ground or eversion if the outside of the foot is coming off the ground.

Essentially, with each pair of agonist and antagonist muscles, one muscle will contract (the agonist muscle) and another will relax (the antagonist muscle) during each movement. Hip Flexion: Decreasing the angle between the femur (thigh) and pelvis. This posture reduces the amount of hip and knee flexion and ankle dorsiflexion needed to reach full depth. (LogOut/ tricep.
