Stationary skiing, unlike cross-country skiing, offers a pleasant reprieve from having to read maps, assess terrain, and negotiate with rude, threatening sasquatches. Fearlessly fly in place with today's Groupon: for $25, you get a month of access to the Skier's Edge machine ($10 per session, up to a $310 value) at CoreVibes Studio. Housed in one of the River Region's only fully outfitted Pilates studios, the Skier's Edge machine enables bodies to develop lateral power while increasing agility and aerobic capacity. Instead of counting reps and grunts, trainees take advantage of the machine's low-impact, cardio cross-training capability, gliding and sliding toward more defined muscle bunches. Tried and true, the technology is often used as a training tool by professional athletes, and a typical workout is known to burn up to 1,350 calories (or 1.34 mega burritos) each hour.
