Instructions
Position the bar so that it is inline with your upper chest. Take an even grip, duck under the bar and then place the bar on your upper back. Place your feet approximately shoulder width apart and out at a slight angle. Disengage the bar by rotating it back. Keeping your eyes up and knees flared, squat down by bending at the knees and bringing your hips back and down. Descend until your thighs are just past parallel to the floor. Ascend by extending knees and hips until your legs are straight.
Tips
For people new to squats, using the smith machine can be useful in learning the squat movement.
