One of the most physical drummers you will ever see is Travis Barker from Blink 182. He really goes for it during shows, soundchecks, and recording sessions. So how does he develop such great stamina? For a while, it was boxing. He boxed–spars with real opponents–three or four times a week.
Travis loves this kind of training and recommends boxing for drummers for several reasons.
(1) It forces you into great physical condition, but aerobically and strength-wise. (2) It’s great for developing superior eye-hand coordination, which is very important when playing the drums. And (3) You learn how to fight and protect yourself, which is never a bad thing when you’re in a famous punk band.
Take it from Travis, too. He was beaten up several times before he got into boxing.
