For whatever reason, I'm having problems with speed bags! I've come close to hitting myself in the face a few times After that, I'd have to say the 'running man' move - again, this probably boils down to lack of coordination on my part! That said, I'm only just starting out (have only done Ph 1, wo 1&2 plus cardio 1) - I'm sure there are a whole bunch more that I'll hate!
fast feet! ergh!
