Quite possibly, the worst invention that has ever been placed on this earth. Many pass it at the gym thinking of it as a waste of space or time, but those are the people who aren't forced to use it every day for a month and a half of winter training. The pain it causes in your ass and legs combined are equivalent to being munched on by rabid raccoons for at least 4 hours.
Coach: Okay everyone today's workout of the erg is a 60 minute steady state, 18-22 rating
Me: *gun to the head*
