Okay, I've been doing my stretches before and after I throw my shotput and javelin and my hips and knees are stiff. At the beginning, I was throwing the shot 8.3 and now I am stiff and can only do 7.8. What do I do? Tryouts are in a week and if I can get a little loosened up, I'll make it for sure... I am still .2 ahead of everyone else in shot, and i dont know about javelin. HELP!!!!!!!!
