Side lunge with medicine ball rotation: "Standing tall with a medicine ball at your bellybutton, if 12 o'clock is directly ahead of you, step with your right foot toward 3 o'clock and tap the medball outside your foot, back by the heel.

You can do this in place as well but doing them moving challenges your balance system and core more."

Squat to jump squat matrix: "Do 10 body weight squats. Follow immediately with 5 jump squats. Rest 60 seconds. Repeat. Rest 45 seconds, repeat. Rest 30 seconds, repeat. Then you can lie down and curse me…"
