Swimmer

Lie on your belly, squeeze your nable inward. Extend your legs and arms. Lift your arms and legs at the same time (palms facing each other) and make small cutting movements with arms and legs. Your shoulders are relaxed all the time, pushing away from your ears.

Yoga Push Up

Start in downward facing dog, lower your arms, hover your chest over the ground to the front, come into upward facing dog. Try to go the same way backward. If possible, keep your knees above the ground when going back. Going back is the hard stuff.

Pike with Slides

Push your hands away from the ground, squeeze your belly in and slightly round your upper back. Your hips are always the highest point. Instead of a slider, you can use a blanket, a towel or any other piece of cloth. Great core exercise!
