1ST Day of Workout and wow!!

After i did some flexibility and dynamic stretches and did the workout. It was a little intense for my hamstrings and i couldnt do 2 of the excersises, but still is it nice. i feel more explosive and powerful when i jump now. My mom is gonna ask a doctor about the springbak insoles and i might get them. Also i found a equation that tells you your potential vertical jump and mine is 61-63 inches!!!!Thats if i worked real hard and stuff so yeh lol..but the workout is really good
