Single-Leg Press
Move · Resistance Training · Movement, Typed Supps
A two-leg press can hide a strength difference between your legs indefinitely; this one cannot.
Stage by stage
- Set-up (One foot, hip-aligned): A single foot on the platform in line with the hip removes any contralateral contribution.
- During the set (Frontal-plane hip control): Gluteus medius and the hip rotators hold the femur and pelvis in line as the sled moves.
- Immediately after (Stabilisation is the limiter): Per-leg load lands well below half the bilateral number because control, not extensor capacity, runs out first.
- Months later (Deficits close): Strength and size differences invisible on a bilateral machine narrow over two to three months.
Muscles trained
- Primary: quads
- Secondary: abs, glutes, hip abductors
Intensity
3.5 METs (Resistance (weight) training, multiple exercises, 8-15 repetitions at varied resistance).
Time to effect
- Weeks: Foot pressure control and stability against the sled's wobble improve quickly, typically within the first couple of weeks.
- Months: Real strength and size differences between legs, often invisible on a bilateral machine, begin to close over 2 to 3 months of consistent per-leg training.

Common myth
"If your two-leg press numbers are even, your legs are equally strong." In reality: A bilateral lift lets a dominant leg quietly take on more of the load without the machine or the lifter ever reporting the split between sides. A single-leg press is one of the few common exercises that makes that kind of imbalance impossible to hide.
