Lower stress levels? Lower risk for injury? Over 500 calories burned? Sign me up! Spin classes are super trendy these days, and with all of their benefits it's no wonder why. In just 45 minutes, you can work up a good sweat while building muscle tone in your gluteal muscles, thighs, calves, and abs. Some classes, like the ones at Soul Cycle, incorporate small hand weights in the workout, so you feel the burn in arm muscles that you didn't even know you had! A lot of people get intimidated by the intensity of spin classes, but with the adjustable resistance and tempo, all levels of exercisers can find an enjoyable level of exercise. The faster you go, the more fat you burn; the slower you go, the more you really work your muscles. So, you can't go wrong! Another plus is the fact that you can do these classes year-round, so when your friends are training for a marathon in 90 degree heat, you'll be inside staying cool (well, as cool as you can be when you're burning 500 calories). Just give a spin class a try, and see what the hype is all about. You'll sleep better, you'll eat better, and you'll feel better!
