I used to bike daily, but with two little kids, it’s nearly impossible to find time to go out on a ride. This year I dedicated myself to getting back on the bike, at least indoors. In May, I bought a Peloton ($1495, plus $39 monthly for classes), and it has truly been life-altering. I’ve been using it most days every week for a quick workout, and my husband — who was initially skeptical of the purchase — has also become a devotee. Eight months later, we’re in noticeably better shape and really glad to be back in a healthier routine. — Rachel Metz, senior tech writer
