Thank you Randy for the 15 minute workout! I think every muscle in my body is going to feel it tomorrow! This is the ultimate cardio 15 minute workout for me! I think I got 200 pitches in just around 15 minutes...I think there's About a 4 second pause in between pitches...GREAT WORKOUT! I don't think I need to jogging now! Went through the whole round with old faithful here!
