I'm looking at bunch of videos about a few postures, snake creeps down and embrace the tiger (just before closing), and it seems that what is important is to keep the back vertical while crouching down - and it seems like the trick to that is to spread the legs and keep one straight.... In other words, almost the split.
Now, the 70% rule and my physiotherapist put together would indicate to me that I can't sink down very low at all. I can't help feeling that I'm missing out on a lot by not even being able to sink to knee level.
Do you think there's a way for a middle-aged man (who was never very flexible) to stretch out the groin over time? What are the things to be careful of and what might be signs of improvement?
Thanks!
