Tighten up those glutes with this exercise from AJ Govoni.
Begin with your back on the mat, knees bent at 90 degrees.
Extend left leg straight up and lift your hips off the mat (picture A).
Pull left knee into your chest while keeping your hips off the ground (picture B).
Extend left leg straight out at a 45-degree angle, keeping knees at same height, side by side (picture C).
Pull leg back to centre and lower hips down. At the last rep, hold position A and pulse up for 10 more reps, really squeezing your glutes at the top.
