Day nine: Squats in a box.
For this you need to do a good deep squat and as you come up you jump round 90 degrees to your right, and keep going round as though you're jumping in a box shape. Jumping and turning 90 degrees after every squat. Give me 9 one way and 9 back in the opposite direction.
Plus, 8 bicycle legs, 7 tricep dips, 6 side lying leg lifts, 5 v sit ups, 4 inchworms, 3 reverse crunches, 2 full press ups and one 30 second plank!
