Day 15 - Turbine

Difficulty - Moderate
Muscle Groups Addressed - Shoulders, Triceps, Core

This is an original. It combines strength and flexibility with slow, controlled, core-engaged motion.

Equipment you'll need:

1. Yourself
2. A floor

Sweet! We all have at least one of each!

Start in a plank position. Core strong, eyes on the floor below you. Tuck your pelvis and keep your back straight. Make sure your butt doesn't sag. No one likes a saggy butt. Hold this position for 5 seconds.

From this position, pick one hand (here, I started with my right hand) and begin to drift it up to the sky. Simultaneously, spin your feet in the same direction so that one foot now rests on the other. Reach your arm straight up and let your eyes rest on your hand. If the balance is still too difficult, keep your eyes focused on a spot on the floor. Keep your body a straight line from your feet to your head - don't let anything sag to the ground. Keep your core tight. Hold this position for 5 seconds.

Now, contracting your core, continue to spin your hand around until it rests on the floor with the other hand. If your shoulders/triceps feel too strained here, you can point your fingers outwards from your body. If you're feeling flexible, point your fingers straight back. Hold a straight-leg table position, with toes pointed up, butt held high, and core tight for 5 seconds.

Again, use your core to come out of the table position twisting again in the same direction into a skyward reach on your other hand. Reach high with your hand and follow it with your eyes. Keep everything straight and calm. Keep the hip raised up. Same principles here, and hold for 5 seconds.

Lastly, spin one more time into a plank position. Take care not to fall into any of these poses. These should be slow, controlled movements. If you're using your core properly and moving slowly, you shouldn't feel any impact on your hands or wrists. Your body should be almost totally relaxed except for your core. Your shoulders and triceps will grow fatigued as well from supporting your weight. Once you've done one full "rotation", come back around the other way.
