For example, when Manny Pacquiao fought Miguel Cotto, the fight was at a catch weight of 145 pounds to accommodate Pacquiao's smaller physique. Boxing has a junior welterweight weight class with a weight limit of 140 and a welterweight weight class with a weight limit of 147.
For power, the impact of each punch can be viewed and monitored according to the section of the workout they are in. Lastly, by monitoring punching power and frequency together over a period of time, coaches and boxers can measure endurance. Currently looking for product development donations on IndieGoGo.com, the Ten Count boxing heavy bag has a goal of $125,000.
