Just got off with 3 stretching series and found out I have a long long way to go in terms of mobility. I'm aware that I'm like a mobility-retard and must work hard on stretching but the question is, how much pain should I endure for each session? If I'm doing say floating pancake for instance, should I squeeze my upper body super hard towards the ground for 60s? Because that should be agonizing for a zombie like me. Or is it good enough to advance just little by little?
Also, I'm having trouble with anterior pelvic tilt shown in the video. Sitting up tall with my legs straight in an L-shape itself is pretty tough for me. So I have to rely on core strength to keep my upper body from tilting backwards. This becomes worse with my legs spread wide(less than 90 degrees though) So if I'm to do any pancake movement, I really have to squeeze my abs to tilt my pelvis forward without curling my upper back. And with all the pancake moves, my abs get burned out and I eventually fail to keep up sitting straight. Can you give me some tips on this? I referred to the scale version and put a block under my pelvis and it became a little bit comfortable. Should I just keep trying from this point?
