Getting in shape, much like speed-reading Russian literature, requires concentration and the strength to forge ahead through painful, protracted inner monologues. Forge ahead toward fitness with today’s Groupon: for $20, you get 10 guest passes to Peak Health & Wellness in Coeur d'Alene, Hayden, and Post Falls (a $150 value).

A trio of Peak Health & Wellness gyms facilitates fitness with a legion of machinery and varied spread of group exercise programs. Weight-room floors play host to both resistance equipment and free weights, and bodies can accelerate their heart rates with the help of treadmills and bikes and by visualizing Freddy Kruger in workout pants. Along with self-made exercise plans, all three hubs corral groups into an array of camaraderie-fueled fitness classes. Cycling or RPM sessions send patrons slinging through simulated courses of mountain peaks, flat-road sprints, and heart-pumping intervals, all conquered from atop a choice of bike or manual-shift mule (advance sign-up required; available two days before each session). Zumba swivels hips to the beat of international tunes at each spot, and BodyPump in Post Falls or Strong in Coeur d'Alene and Hayden sculpt corporeal forms with the aid of adjustable-weight barbells (Strong requires advance sign-up; available two days before each session). Wind down in Coeur d'Alene or Hayden's centering yoga sessions or in any of the three gyms' saunas, which leave visitors as relaxed and damp as a recently docked submarine.
