I've been doing all three stretch series each one once a week since they have been released. It's funny but only about a month ago I started to get quite intenstive DOMS especially after the front split and also a little less after the middle split series. Or at least it's what I think is called DOMS. A strange kind of feeling in the glutes that feels a little bit like something in between growing pains and muscle soreness. It lasts for about the two following days after an evening stretch session.
I have actually two things that I'm wondering about:
1. Why did this start only about a month ago and not from the beginning? Could it have to do with a new range of motion becoming accessible? I don't think that the effort that I'm putting into the stretches has changed. But I notice (small, but real) new ranges of motion.
2. Is it a sign that I'm doing too much?
