I only had 20 minutes to workout before taking kids to school. @wesokerson said it was enough time. He was right. Here it is Leg Workout: With some upper body/and cardio Nordic hamstring Curl x 12 (Focus on the down phase and help yourself up by pressing with arms) Thrusters x 12 Bench step overs x 20 (10 each side) Step up knee drive x 20 (10 each side) complete all four exercises then take a 1 min. Break 4-5 rounds 15/20 min total work time
