Exercise
The leg press is one of the most popular machine exercises for the legs, performed on a dedicated leg press machine. It is a closed kinetic chain exercise in which a platform is pushed with the feet against resistance. It is an excellent alternative to squats for those with back problems, as the spine is supported.
🎯 Primary Muscles
Quadriceps, gluteus maximus, hamstrings.
🔧 Secondary Muscles
Adductors, calves, core stabilizers.
⚡ Exercise Type
Multi-joint compound exercise. Safer for the spine than squats.
📊 Difficulty Level
Easy. Suitable for beginners, easy to learn the technique.
📋 Technique
1
Position on the Machine: Sit down with your back and head pressed against the support. Feet on the platform shoulder-width apart.
2
Foot Position: Standard: feet in the middle of the platform. Higher = more glutes. Lower = more quadriceps.
3
Unlocking: Extend your legs and unlock the safety catches. This is the starting position.
4
Lowering: Slowly bend your knees. Lower until your knees are at ~90°. Do not go too deep.
5
Pressing: Press firmly through your heels, returning to the starting position. Do not fully lock out your knees.
6
Breathing: Inhale as you lower, exhale as you press. Protect your lower back — it must remain pressed against the support.
💪 Muscles
| Muscle Group | Muscle | Role |
|---|---|---|
| Thighs (Front) | Quadriceps: vastus lateralis, medialis, intermedius, rectus femoris | Primary — knee extension |
| Glutes | Gluteus maximus | Hip extension, especially with a high foot position |
| Thighs (back) | Hamstrings | Secondary Hip Extension |
| Adductors | Adductors | Stabilizes the legs |
⚠️ Mistakes
- Lowering Too Deep: The glutes lift off the support. This is extremely dangerous for the lower back.
- Knee Locking: Full knee extension at the top. Maintain a slight bend.
- Pushing Knees with Hands: Hands help push the knees. This is a sign that the weight is too heavy.
- Weight on Toes: Heels lift. The weight should be through the heels.
- Too Narrow/Wide Foot Position: Experiment, but avoid extremes without supervision.
