Front Squat - Begin by standing with the bar up to your shoulders. Elbows should be bent back so that you have a grip on the bar with the hands facing upward. Bend down, keeping an arch in the upper back, feeling the impact of the weight. Progress to a point where you are still comfortable with the weight, then go back to a standing position.
Straight Leg Dead Lift (works Hamstrings) - Start in a standing position, holding the bar with your arms hanging down. Start with a small weight so as not to over strain the arms or back. Slowly lower your upper body by bending forward, keeping your knees locked, with an arch in your upper back. Lean down until the bar is near the floor, then slowly come back up to a standing position.
