This video reminds me of the first time I tried the sport of boxing as a fitness trainer. My sister finally dragged me to a boxing gym with her and I thought I was in pretty good shape. Man was I wrong! Boxing humbled me because I was only able to last ten minutes... and I was a professional trainer. Boxing is a true complete workout and conditions you in a way no other format can. If you have never tried a boxing workout I highly suggest you do. Its addicting! You will never forget it.
