1. Using a leg press machine, sit down on the machine and place your legs on the platform directly in front of you at a medium (shoulder width) foot stance.
2. Lower the safety bars holding the weighted platform in place and press the platform all the way up until your legs are fully extended in front of you. Make sure that you do not lock your knees. Your torso and the legs should make a perfect 90-degree angle. This will be your starting position.
3. Inhale and slowly lower the platform until your upper and lower legs make a 90-degree angle.
4. Pushing mainly with the heels of your feet and using the quadriceps go back to the starting position as you exhale. Repeat for subsequent repetitions and ensure to lock the safety pins properly once you are done to avoid the platform falling on you fully loaded.
WARNING! Always check to make sure that when you re-rack the weight the platform is securely locked.
