Remember yesterday we did some donkey kicks? Now we are further isolating the glutes by holding the donkey kick high, and including just really small movements. Note that the lower back does not move at all; just your butt (you may need a mirror). You REALLY feel this in your bum. Try 20 reps on each side, rest, and repeat for 3 or 4 sets.
Cheers Eights & Weights!
