C'mon, admit it: Your leg muscles could use a wake-up call. Try immersive cycling, which, unlike a traditional spin class, guides you through a series of high-intensity interval-training challenges while transporting you out of the studio through an Imax-like screen. You'll be peddling through a virtual forest or racing on a simulated bike track. Since you're constantly changing positions in the saddle, be sure to wear pants with a seat lining. "Ultracor's styles are designed by a cyclist, so they have extra protection," advises Caroline Gogolak, co- founder of fitness platform Carbon38.
