Begin on all fours and lift your right leg off the floor until your knee is in line with your hip.
Flex your foot and squeeze your glute to raise your heel an inch toward the ceiling. Continue these small, concentrated pulses.
Open your right knee out to the side, keeping your foot flexed, and pulse your leg one inch to the left. You are not trying to lift the knee up, but try to keep it level as it moves behind you. You should feel your glutes firing away as you pulse.
