Instructions

1

Sit on the leg press machine with back and head resting firmly against the padded support. Position feet on the platform shoulder-width apart with toes pointing slightly outward. Maintain neutral spine alignment throughout the exercise.

2

Place both feet flat on the platform with heels approximately 12 inches from the platform edge. Grip the handles on either side of the seat for stability. Ensure core is engaged and lower back remains in contact with the backrest.

3

Slowly lower the platform by bending knees, allowing them to track over toes without caving inward. Lower until knees reach approximately 90 degrees of flexion, ensuring knees do not extend past toes. Maintain control throughout the lowering phase.

4

Drive through heels and mid-foot to extend knees and push platform away from body. Return to starting position with slight knee bend (do not lock knees at top). Maintain constant tension on quadriceps throughout the movement.

DIFFICULTYBeginner

Overview

If you want to isolate and overload the Quadriceps, the Lever Single Leg Extension plate loaded is an excellent addition to your routine. The mechanics of this Strength exercise specifically bias the Thighs, while the use of Leverage machine allows for a smooth, natural resistance curve.

Benefits

Promotes balanced muscular development by effectively recruiting the Quadriceps and associated synergists.
Improves overall Thighs stability and proprioception during heavy loads.
Allows for a natural movement path that closely mimics functional daily activities.
Acts as a highly scalable Strength movement, perfect for both beginners and elite athletes.

Common Mistakes

Failing to achieve a full range of motion, which drastically limits Quadriceps engagement.
Losing core tension, leading to poor spinal alignment and reduced power output.
Using excessive momentum to swing the Leverage machine rather than controlling the eccentric phase.

Pro Tips

Control the eccentric (lowering) phase of the Lever Single Leg Extension plate loaded for 3-4 seconds to drastically increase time under tension.

Muscle Anatomy

The primary driver is the Quadriceps. However, the movement also recruits Gluteus Maximus, Hamstrings, Adductor Longus, Rectus Femoris to maintain control of the Leverage machine.
