If you think yoga is good try the new stretch routines...
I don't need any further proof that this movement is majorly hampered by flexibility when I watch my young daughter from a supine position on the floor stand up without help from anything but her legs, and multiple times in a row to boot. I laugh cause I tell my friends how amazing that is and they claim they can do the same...no big deal. I've yet to see one of them sit up, tuck legs under, and stand up without using momentum. Anyone that has tried just doesn't have the flexibility to complete it. Then start asking about this gymnastic stuff...
Coach wouldn't say had it to him he'd probably say stop talkin and show me 15 perfect ones..;D
