This fellow is extremely flexible and clearly a master of his art, but don’t let that intimidate you. We can all benefit from these movements. Short-duration, active stretching is a great way to increase range of motion and wake up your nervous system before a workout or sport. Just GO SLOW, observe the positions, and even if you start with limited range, you will make increases over time.
He gives special attention to toes and feet. At first I could hardly fit my fingers between my toes. Hang in there with that one, runners!
Be careful with the ones where hips are in the air. This puts some strain on the lower back. Try putting pillows under your low back to prop up, and make sure to engage lower abdominals.
Let me know how it goes.
