I picked up the Domain Cycling Extra Large Gel Exercise Bike Seat Cushion Cover, Stationary Recumbent Bicycle Rowing Machine seat cushion for $36.99 after months of dealing with lower back pain during my stationary bike sessions. As a Marine veteran who spent years in uncomfortable positions, I thought I could handle anything. Turns out, that attitude doesn’t hold up when you’re spending 45 minutes on a bike seat that feels like concrete. The Domain Cycling brand promised something different, and I wanted to see if their gel cushion cover would actually make a difference in my home workout routine.
