Coach Lawson: bodybuilding breakdown
U.S. Air Force Airman 1st Class Matthew Moore, 27th Special Operations Contracting Squadron contracting specialist, executes a proper squat on the Smith Machine in the Fitness Center at Cannon Air Force Base, N.M., July 19, 2012. With head up, lower back arched and abs tight, begin the movement by bending at the knees and squatting towards the ground until your thighs are just below parallel to the floor.
Drive the weight, while exhaling, back up until you are in the standing position without locking your knees. (U.S. Air Force photo/Airman 1st Class Alexxis Pons Abascal)
