Possessing great cardio or a "bigger gas tank" than your opponent can be the difference between winning and losing. It is what separates the good fighters from the great ones. Get your cardio to the highest level possible and without hurting your wallet!
The mask fits great and with the additional strap secures it in place well. There are no directions so figure it out yourself. The timer seemed hokey, I chucked it. One more jump rope, might use it some day.
Was this a gift?:
Bottom Line Yes, I would recommend this to a friend
