Hey. I didnt want to invade Chadderz thread so im making my own. I want to do the splits. For being 320lbs im surprisingly flexible. With side splits im about 8" inches from the floor. Now the real shocker is with front splits. I was stretching at home with my 6 year old. She does gymnastics and is watching the instructor give her and others correction...(you can see were this is going...) So she was doing her front split and wanted me to do mine. I told her i would try but i would not likely get past a awkward lunge. So i maneuvered into front split position and started going down.. I managed to get way lower then i thought i would be able to. My daughter said my legs were wrong. So she grabs my right leg(twords the rear) and straightens it out.(it was bent at a angle) In that act of straightening she somehow pulled me more inches down. In fact i was closer to a full front split then she is. maybe 3-4 inches if that,(she indicated my depth with 2 fingers spread apart, saying i was this far. which was like 3 inches or so). Now my question is, what should i be feeling for with regards to the safety of my muscles. I could feel the muscle stretching and it felt like i had a large rubber band and was pulling both ends hard. It was kinda scary as it wasnt entirely painfull but the stretching effect i felt in my muscles scared the heck out of me. So the question is, how do i know when to stop? What feeling should i be looking for that says your muscle is at its limit? I am certain i could have gone lower, but my fear kicked into near panic as the stretching effect i was feeling kept increasing. Im not describing it, that feeling of pulling a handful of rubber bands apart. Now i have no pain today and no ill effects so im sure i could have gone lower but i need to know what to feel for how to tell when to stop. Its this not knowing thats stoping me from going lower on the side splits. Im sure i could go lower but the stretching/pulling effect frightens me.
