Simple. Brutal. Uncomplicated. This is a workout you don’t have to think about. You just get on, drive yourself into the ground, and get off. It’s the perfect video for anyone who needs to fit a killer, high-intensity workout into their lunch hour to tune-up for racing or weekend ass-kicking. It’s also the necessary evil: if you want to watch only ONE Sufferfest video to make you faster, this is it.
