Stand upright and balance on one leg (e.g., left).

Bend the other leg (right) behind you, bringing the heel towards your glutes.

Extend arms forward for balance.

Slowly lower into a squat on the standing leg, keeping your torso upright.

Descend until the knee of the bent leg lightly touches the ground behind you (or as low as possible without touching).

Push through the heel of the standing leg to return to the starting position.

Maintain balance throughout. Repeat for desired reps before switching legs.
