Sled 45 Degrees Leg Press
The sled 45-degree leg press is a compound machine exercise designed to build strength and mass in the quadriceps, glutes, and hamstrings. It allows you to train the lower body with heavy loads while minimizing spinal compression, making it ideal as a primary lift or a follow-up movement on leg day.

How to do it
- Sit on the leg press machine with your back and head resting comfortably against the padded support.
- Place your feet shoulder-width apart on the sled platform, positioned at a 45-degree angle.
- Bend your knees and bring the platform towards you, keeping your feet flat.
- Inhale and brace your core. Exhale as you press the sled away, extending your legs fully.
- Focus on using your quadriceps, hamstrings, and glutes to push the weight.
- Avoid locking your knees at the top of the movement.
- Slowly return the sled to the starting position, controlling the movement and keeping tension in your leg muscles.
Common mistakes
- Rounding the lower back off the pad at the bottom of the movement places dangerous shear stress on the lumbar spine.
- Locking out the knees forcefully at the top transfers load away from the muscles and directly onto the joint structures.
- Allowing the knees to cave inward during the press causes knee valgus and increases the risk of ligament strain.
- Lifting the heels off the sled platform shifts excessive pressure onto the balls of the feet and patellar tendons.
Tips
- Pull tightly on the side handles throughout the entire set to keep your hips anchored to the seat.
- Place your feet higher on the footplate to emphasize the glutes and hamstrings, or lower to focus more on the quads.
- Lower the sled under strict control for two to three seconds rather than letting gravity drop the weight.
Sets and reps
For muscle growth, aim for 3 to 4 sets of 8 to 12 reps with 2 to 3 minutes of rest between heavy sets. For muscular endurance, perform 3 sets of 15 to 20 reps with 60 to 90 seconds of rest.

Questions
Is the 45-degree leg press safe for the lower back?
It spares the spine from vertical axial loading, provided the pelvis stays firmly against the backrest throughout the rep. If you feel any sharp lower back pain, stop immediately and consult a healthcare professional.
Can the sled leg press replace barbell squats?
It provides exceptional quadricep and glute overload with less fatigue on the stabilizing core muscles, making it a great supplement or alternative, though it does not train full-body balance like squats.
