Pilates and strength training, sitting in a tree. K-I-S-S-I-N-G.

First comes love, then comes marriage … then comes their awkwardly large love child: the Megaformer.

After gaining a frenzied following in L.A., the fitness craze makes its Midwest debut at Lincoln Park’s newest studio, Body R+D.

The Megaformer is like a Reformer on crack. Stable benches bookend a sliding platform; add-ons — straps, poles, bungee cords, handlebars — are incorporated throughout various exercises. Small, repetitive movements using springs, pulleys, and your own body weight result in extreme toning and tightening (resistance levels are customized).

Ten-person, 50-minute workouts allow for personal attention; an unexpectedly upbeat sound track helps ease the pain. (Spring Awakening has never sounded so good.)

The next day, your ass will be on fire.

Hey, sometimes love hurts.
