After analyzing each exercise in the chart, break each into two primary movement phases, such as a lifting phase and lowering phase. For each phase, determine what ankle and foot joint movements occur, and then list the ankle and foot joint muscles primarily responsible for causing/controlling those movements or maintaining the position. Beside each muscle in each movement indicate the type of contraction as follows: I-isometric; C-concentric; E-eccentric.
