How to Do a Crossover Hamstring Stretch
Lengthening your hamstrings and outer hip muscles is easy if you know the right stretch. All you need is a doorway and a little bit of effort and you'll be on your way to stronger, more flexible legs and hips in no time. Firstly Lie on your back. Both of your legs should be straight, with your arms spread out to your sides and your head facing upwards. Secondly, Take your outer leg and lift it into the air. Cross it over your other leg. Once you've stretched your initial outside leg, rearrange yourself (so that your other leg is the one you're crossing over). Finally, Do this exercise for 45 seconds to 1 minute per set. Repeat until you've completed 6 sets (3 per side).
