On the first day of Fitness
My Y Coach gave to me
One minute of high knees by the tree.
The first step to any exercise program is to get your body warmed up and ready to move. High knees are a good way to loosen up your joints and get your body ready for the exercises to follow. You can perform this exercise as a low-impact or high impact exercise based on your current level of health and physical activity.
