My kickboxing / muay thai instructor makes me do between 50 - 165 burpees almost every session. Despite doing this kind of exercise for some 9 months it doesn't seem to get any easier and I ALWAYS feel sick after ten of them. Please can anyone tell me:

(a) does it ever become any easier (i.e. will I ever stop feeling sick? - no other exercise makes me nauseous)?
(b) will tweaking the technique make them easier to deal with? - at the moment on the jump I can't look up - I have to concentrate on the spot on the floor where I look when on the squat thrust part of the burpee.

I'm asking because the burpees are the bits I dread in every session...
