Stand upright, balancing on one leg (e.g., right).

Extend other leg (left) straight forward.

Extend arms forward for balance.

Slowly lower into a single-leg squat, keeping extended leg off ground.

Descend only partially (e.g., until thigh is parallel to ground, or to a comfortable depth where balance is maintained).

Keep back straight, core engaged.

Push through heel of supporting leg to return to start.

Repeat for desired reps, then switch legs.
