The leg press (45 degrees) is a machine exercise that targets the quads, glutes and hamstrings. Here are the steps to perform it correctly:
Sit on the machine and place your feet on the platform, shoulder-width apart. Adjust the seat and the safety pins to suit your height and range of motion.
Press the platform away from you until your legs are fully extended but not locked. This is your starting position.
Slowly lower the platform until your knees form a 90-degree angle or slightly lower. Keep your feet flat and do not let your knees cave in or out.
Push through your heels and extend your legs to return to the starting position. Repeat for the desired number of reps.
