How To do Leg Press
1. Sit down to the machine so that your hips and back are fully attached to the sitting pad. Your feet should be shoulder-width apart. (Narrow your feet will affect your outside of the thigh, wide your feet will affect the inside.)
2. Remove the safety pin, feel the weight and bend the knee.
3. Lower the weight plate to a depth where the hips and waist do not float from the pad.
4. While maintaining the strength in the abs, push up the weight plate.
"If you can't control the movements, you will need to reduce the weights. Proper form is more important than the amount of weight you're lifting."
