ive never done it on rollers (hoping to someday), but done it on a spin bike in the gym... And i know exactly where your coming from! Hope you are able to walk straight... i know i sure couldnt :P
Have an emotion rollers and done all my intervals on it including the Haunted, HHNF, and fight club. Definitely need to have something grab onto after some of these intervals espicially those last 8sec of the Haunted.
