Single-Leg Press
- Beginner
- Machine
The single leg press puts one foot in the center of the sled and presses it away by extending the knee and hip. Because the back and hips stay pinned to the pad, the quadriceps take the bulk of the load with the glutes, hamstrings, calves, and adductors assisting. Foot position steers the emphasis: pressing through the heel brings more glute in, pressing through the ball of the foot keeps the quadriceps dominant. Stopping just short of a hard lockout keeps tension on the muscle and keeps the knee joint out of an end-range jam.
How to do the Single-Leg Press
- Set the seat so your working knee starts bent without your hips rolling off the pad.
- Place one foot flat in the center of the sled and let the other leg rest clear of it.
- Grip the handles, press your lower back into the pad, and release the safety catches.
- Lower the sled under control until the working knee reaches roughly a right angle.
- Drive the sled away by extending the knee and hip, stopping just short of lockout.
- Complete the reps on that side, reset the safeties, and switch legs.
Muscles worked
- Primary:
- Quads
- Secondary:
- Glutes, Hamstrings, Calves, and Core
Why train it
- Loads the quadriceps heavily while the spine stays supported.
- Isolates one leg so strength differences cannot be masked by the stronger side.
- Offers a controlled path, which makes it easy to prescribe early in a program.
Common mistakes
- Locking the knee out forcefully at the top, which dumps tension into the joint.
- Letting the hips roll off the pad at the bottom, which rounds the lower back under load.
- Loading the sled too heavily, which is the main cause of knee and back complaints on this machine.
- Letting the working knee drift inward instead of tracking over the foot.
Frequently asked questions
What muscles does the Single-Leg Press work?
The Single-Leg Press trains the quads as the main target. Expect the glutes, hamstrings, calves, and core to take some of the load as well.
What equipment do I need for the Single-Leg Press?
The Single-Leg Press needs a machine. Nothing beyond that is required to run the movement the way it is described above.
Is the Single-Leg Press suitable for beginners?
Yes. The Single-Leg Press is rated beginner, and the machine holds the path for you, so there is little to get wrong once the seat and the pin are set.
Can I do the Single-Leg Press at home?
Only if your home setup runs to a machine. Most do not, so this is usually a gym movement. The alternatives below cover the same muscles with kit you are more likely to have.
How many sets and reps of the Single-Leg Press should I do?
Three to five sets of 5 to 10 reps. Rest two to three minutes: squats tire the whole body, and a rushed second set is where depth and bracing fall apart.
What are good alternatives to the Single-Leg Press?
Band Squat, Bodyweight Box Squat, and Dumbbell Front Squat train the same primary muscles as the Single-Leg Press. Pick whichever one matches the equipment in front of you.
