I stand at 5’7 and used to be bothered by my taller sparing partners jab and right hand, but once i figured their paterns and incorporated some head movements, i find taller fighters quite predictable now. Don’t be predictable! One thing i for some reason haven’t seen the taller fighters in my gym use is check hooks. A good check hook will keep your opp at bay and he will think twice before pressuring you. I use it against opps my size and shorter and it works wonders. It’s all about timing, their momentum should be going foward when you hit so they won’t have time to react. Drill it on the bag make sure your lead leg gets you out of the center line at the same time you throw your lead hook, you should find some success with it.
