High knees
Run on the spot making sure you raise your knees higher than your hips. Make sure you keep your elbows at 90 degrees and drive your elbows back and swing your arms forward to the height of your forehead.


Squat down as low as you can and push your bum back. Lean forward and keep the weight on the balls of your feet. Move your feet up and down as quickly as you can by only moving your feet one to two inches from the floor.


Star crump thrusts
After performing the star crump you are going to jump your knees under your body by bending your hips and knees. Bring your feet as high up as you can as you jump your feet forward and then jump your feet back.


Triceps push ups
Like the push up, but have your hands are shoulder width apart. When you lower your body make sure your arms squeeze your ribs.

Plank with hip dips
Elongate your body by having only your toes and elbows in contact with your body. There should be a straight line between shoulders, hips, knees, and ankles. Rotate your hips by moving them towards the floor to your right and then left. Do as many reps as you can.
