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.
