David Beckham can make a common quad stretch look sexy. The Pilates instructor in me, however, take issue with his form. His stretching form, that is.To see how Becks can improve his technique, simply read more.
Let me start with a positive comment. I think it is great that these teammates are supporting each other for balancing assistance so they can focus on their stretching. However, David should have the insides of his knees touching. Doing so increases the stretch on the outside of the thigh, the lateral quad muscle which tend to be much tighter than the inner quad. When the knee cap on the leg you're stretching is not pointed directly at the ground you can stress the inner portion of the knee joint.
If I were stretching with Beckham, I would tell him to increase the stretch by squeezing his glute max (the large muscles in the behind) rather than pulling heel closer to his bum. Next time you stretch your quad, think of Becks but remember these pointers too.
