PLANK LEG EXTENSION
Starting on all fours or a plank position, with the shoulders over the wrists and the abs engaged, lift your left leg directly behind your body, slightly turning the leg out and pointing the toe. Lift the leg up and down while engaging the glute. Be careful not to let the lower back arch. Repeat eight times on each leg.
In the same position, pulse the lifted leg three times, keeping it turned out and pointed. Repeat four times on each leg.
From a plank position, extend the left leg out. Draw it in to tap the right elbow, then sweep it to the left before returning it to the starting position. Repeat eight times on each side.
While on all fours, or in a plank position, lift the left leg up and then outward, tapping it to the side and then returning to the start position. Repeat eight times on each leg.
SIDE LEG LIFTS
From all fours, lift the left leg up and bring it out to the side of your body, making a 90-degree angle. Lift until it’s nearly parallel to the ground, then return to the starting position. Repeat eight times on each leg.
PLANK LEG AND ARM PULSES
While on all fours, lift the left leg and right arm simultaneously and pulse eight times. Repeat on the opposite side.
