Hi, this is something I came across a few months ago. I'm posting it for the novelty value as much as anything. It's a stretching technique for the hip flexors which looks like nonsense on stilts. When I saw the demonstration video I was very sceptical - then I tried it and found that amazingly it worked for me. It worked very well in fact. I'm quite tight in the hip flexors, so the results for me were quite dramatic - and instant!!!!
(No, it's not waiting out the tension, or PNF, or anything else you are likely to have heard of!)
Does it work for anybody else on this forum? Try it and let me know - if only to satisfy my curiosity!
PS If you know a way to apply this to other muscle groups, I'm listening!
