Flexibility is the key to unleashing power and speed by increasing the range of motion active (agonist) muscles have to travel before they are held back by the opposing (antagonist) ones. Being more flexible can also reduce the chances of injury when exercising, though the biggest benefit will be in the way you walk and stand. This 30-day program will help you increase your flexibility. The program utilises a mixture of active (leg raises) and passive (holding the splits position) stretching techniques to give you the fastest gains possible in the shortest time.
Tip: it will help if you also do long distance running. Do the side splits right after the run when your muscles are all warmed up.
