Movement Analysis: Squat Kevin Forsyth
2
Proper Squat Technique Stand straight with knees relaxed, feet hip-width apart and toes slightly turned out. Bend your knees, tilt your hips back and slowly lower your behind, like you're going to sit in a chair. Keep your back straight and upper body muscles in a tight contraction, so all the work is done by your legs. Squat down until your thighs are parallel to the floor. Don't let your behind drop below your knees or your knees go in front of your toes. Lift up slowly from the squat by pushing with your heels and using only the strength of your legs. Keep abdominal muscles tight and your back straight.
