1 - Start by selecting the desired weight on the leg press machine. Sit on the machine with your back flat against the backrest and your feet shoulder-width apart on the platform in front of you.
2 - Adjust the seat so that your knees are bent at a 90-degree angle when your feet are on the platform. Make sure your knees are aligned with your toes.
3 - Place your hands on the handles on either side of the seat for support. Take a deep breath, brace your core, and push the platform away from your body using your legs.
4 - Extend your legs fully, but do not lock out your knees. Keep your back flat against the backrest throughout the exercise.
5 - Slowly lower the platform back down towards your body, bending your knees until they are at a 90-degree angle again.
