When I first started yoga 4 years ago, I couldn't bend in a forward fold properly or touch my toes while sitting down. I've gradually increased my flexibility, but for at least the first year, my hamstrings would feel sore the next day almost every time. It felt like DOMS (delayed onset muscle soreness) to me, so I figured I was building up strength. But I haven't heard anyone else mentioning this, so is it possible the soreness is from overstretching?
I didn't find the right solution from the Internet
