Why: Butt kicks engage the hamstrings and accentuate the recovery portion of the running gait and improve leg turnover cadence.
How: Run in place with your thighs more or less locked in a neutral position and try to kick yourself in the glute with your heel on each stride. Focus on keeping the rest of your body still and simply flicking your lower leg backward. If you’re not making contact, you need to improve your dynamic range of motion. Do two or four reps of 15 kicks with each leg.
