Did you know there is more than one way to use a leg press
The leg press is an excellent piece of equipment that can be manipulated to target different parts of your legs. In particular, changing your foot positioning can change the area of activation.
(Legs are not something you can fully isolate, but can to a degree!)
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. 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. As you inhale, slowly lower the platform until your upper and lower legs make a 90-degree angle. Pushing mainly with the heels of your feet and using the quadriceps go back to the starting position as you exhale. Repeat for the recommended amount of repetitions and ensure to lock the safety pins properly once you are done. You do not want that platform falling on you fully loaded.
Caution: Always check to make sure that when you re-rack the weight the platform is securely locked.
