As a whole (all heads working together), the pectoralis major assists adduction (lowering upper arm from side raise position to the midline of the body), medial rotation (rotating upper arm forward or inward to the midline of the body) and horizontal flexion (moving the upper arm from a side raise position to the front of the body).

Correspondingly, the five phases that can be described between these positions are as follows: (1) the first pull happens between the ground and when the bar reaches knee level and is initiated by knee and hip extension; (2) the transition happens when the barbell is between knee level and the power position and involves a shift in the position of the body relative to the barbell, which involves a brief period of knee flexion and is therefore referred to as the double knee bend (Enoka, 1979; 1988); (3) the second pull is the most powerful phase of the lift and occurs while the barbell is between the power position and the lifter is in triple extension; (4) turnover occurs as the lifter quickly drops down under the bar from the triple extension position to the catch position, in a deep front squat; (5) recovery into the standing position occurs as the lifter stands from the catch position to upright.

So seated plantar flexion exercises may benefit most from a focus on type I muscle fibers.

As ankle plantar - flexion angle increased from -15 to 15 degrees, the moment arm length increased linearly.

Assessing in flexion also removes any additional restriction coming from the external rotators that cross the hip joint at the front (e.g. iliopsoas, sartorius, pectineus and adductors brevis and magnus).

The lateral (side) deltoid is involved in many of the same movements as the anterior deltoid: abduction (moving the arm away from the body), flexion (moving the arm upward to the front), and transverse flexion (moving the arm across the chest).

Plantar flexion is the ankle movement of moving the foot down, pointing the toes away from the body.

However, noting the significant gain in hip extension in the intervention group from prelunge to postlunge in the second session and comparing them to the results reported by Macdonald et al. (6) of immediate gains in knee flexion angle post foam rolling, it is reasonable to conclude that the effects of foam rolling are immediate, even in a dynamic movement, but do not remain for longer bouts of time.

In general, it seems that exercises from the knee flexion category (i.e. leg curls) almost always feature as one of the best exercises, while exercises from the hip extension and knee extension category (i.e. squats) never feature as one of the best exercises.

Key shoulder movements that involve the pectoralis major include shoulder horizontal adduction (moving the arms together in the transverse plane at shoulder height), shoulder adduction (moving the arms down to the sides, from shoulder height), shoulder scapular flexion or extension (moving the arms to or from shoulder height in the scapular plane in front of the body), and shoulder flexion or extension (moving the arms to or from shoulder height in front of the body).
