What it is
A leg press done one leg at a time, with the other foot resting off the platform. It exposes and fixes left-right strength differences while keeping the back supported. Use a lighter load than your two-leg press and keep the knee tracking over the toes.
One side at a time: log each side, and match the reps of your weaker side.
Technique tips
- Center the working foot on the platform
- Keep your hips and lower back on the pad
- Lower until the knee reaches about 90 degrees
- Push through the whole foot without locking out hard
How to track your progress
Log the weight and reps of each set. Straddly turns every set into an estimated one-rep max, so a heavier single and a strong set of eight both count as progress, and it flags a personal record the moment you beat your best.
