Not stiff or firm but loose when launching the ball like it should be. My friends told my it look like i was throwing like 79 mph lol. But one fastball out of the 50 i threw was very very hard.Can someone explain this. I was pushing off, loadin and driving with my body consistently. But this one fastball sort of hopped towards the plate!!!
After that It slowed down again!
IDK WHAT TO DO. firm arm or rag loose?
