So i start classes on the 20th and im really stoked, on problem is that i havent stretched in a little over 2 months. Im starting to stretch when i wake up and when i go to sleep, but i dont feel any looser. Anyone got any suggestions? I also heard that core strength is a must and so is flexability. I do 50 sit ups everynight along with 50 lower ab workouts, it feels tighter but i dont feel any results. PLEASE HELP!
