4. Ski Twists
No time to hit the slopes this winter? Well, this is ski move that can be done in your living room and is far more interesting than the plain old jumping jack. For this exercise, start by keeping your feet together and twist at the hips while jumping and twisting to the left, then back to the center. Then twist right and back to the center, etc. This exercise works the rotary function of the body’s core while simultaneously burning lots of calories.
