Targets: Glutes, hamstrings, and quadriceps.
(A) Begin in standard plank position.
(B) Lift your right leg three inches off the floor, pointing your toes and keeping your leg straight. With your torso completely still, gently and quickly pulse your leg up and down five times, firing up your glutes, hamstrings, and quad muscles. Return to the starting position. This is one rep. Repeat 9 times, then switch sides and do 10 more.
