The bike was effective, but it wasn’t sustainable. Hull says the daily rides began to feel “less doable” as he bored of the monotony. Rather than quit, he took this as an opportunity to try something new: jumping rope. This was the perfect fitness tool for a touring musician, since it could fit in a small bag and be used anywhere—but it required a higher bar to entry than a stationary bike. “I said some of the most outrageous stuff out loud to myself that I’ve ever said failing for months at jump rope,” Hull admits.
