Can I test my punch power?
Guru generally rounds up a volunteer or two from the housekeeping staff and asks them for ratings, but that’s both unscientific and, apparently, inhumane, so other methods are required. There’s a free Android app (Punch Power) – clutch phone in fist, throw a haymaker at the air and it’ll offer up some spurious figure. It’s rubbish and will likely break your phone.
Hykso’s Punch Trackers ($228) do a similar job but with a bit more focus. A bundle of accelerometers to strap to your gloves when training, they track the arc, power speed and frequency of your swings, so you’ll get a lot more than a number on how hard you thump.
