Single-Leg Extension
The leg extension one leg at a time, which shows up any difference between sides.

How to do it
Setup
In the leg extension machine, one shin behind the roller, the other foot resting.
Steps
- Extend the single leg to straight.
- Pause at the top.
- Lower under control; finish the leg, then switch.
Common mistakes
Half the machine's two-leg weight is still too much: singles run lighter than half. Hips twisting toward the working leg: square on the seat. Kicking: smooth to the top.
Breathing
Exhale extending, inhale lowering.
