Back squat with barbell

When properly performed, the back squat is an excellent exercise for developing the strength of the torso and lower extremities. Throughout the movement, the spine should be maintained in a neutral position (without flexion or excessive extension) and the hips, knees, and ankles should travel in the same sagittal plane. Squats should be performed to proper depth (ie, femurs below a parallel relationship with the ground) in order to engage the hamstrings and adductor muscle groups and to develop mobility.
