1 RM Leg Press

What This Test Measures

• This test measures your lower body maximal strength, particularly in the quadriceps, hamstrings, and gluteal muscles.

Equipment Needed

• Leg press machine
• Weight plates
• Spotter (recommended)

How to Perform the Test

1. Begin with a thorough warm-up, including light cardio and several warm-up sets of leg press with progressively heavier weights.
2. Sit in the leg press machine with your back against the pad and feet on the platform about shoulder-width apart.
3. Release the safety catches and lower the weight under control until your knees form approximately a 90-degree angle.
4. Push the weight back up to the starting position without locking your knees.
5. If successful, rest 3-5 minutes and attempt a heavier weight.
6. If unsuccessful, rest 3-5 minutes and attempt a lighter weight.
7. Continue this process until you find the maximum weight you can lift for one complete repetition with proper form.
8. Record this weight as your 1 RM.

Tips for Best Results

• Always use the safety catches on the leg press machine.
• Keep your back flat against the pad throughout the movement.
• Don't lock your knees at the top of the movement.
• Keep your feet flat on the platform and avoid letting your heels rise.
• For beginners, consider using the multiple-repetition method to estimate 1 RM.

Interpreting Your Results

• Your 1 RM leg press is compared to normative data based on age, gender, and body weight. It can be expressed as an absolute value or relative to body weight (1 RM ÷ body weight). Higher values indicate greater lower body strength.
