Like a good horror movie, a good exercise regimen shocks the body out of its lethargy, which is why so many personal trainers chase their clients on treadmills while brandishing chainsaws. Get in less terrified shape with today’s Groupon: for $20, you get one month of unlimited boot-camp classes (a $99 value) at Genesis Fitness in Nampa. Camps are currently held at 9 a.m., noon, and 6 p.m. daily, but more times may be added.

A neighborhood supergym, Genesis Fitness prods out-of-shape bods toward healthy gains during 30-minute full-body boot camps. Experienced instructors keep their ragtag regiment of sweat donors in constant motion with a circuit workout of cardio drills and muscle-amplifying exercises designed to increase strength, stamina, agility, and quickness, as well as give them the confidence to stand up to the city pool's shark bully. The bodies of men and women alike exorcise excess pounds from the carefully crafted routine's many surprises and plot twists, and the group environment keeps each member motivated to top themselves. Each one-month training montage begins with a club orientation, fitness assessment, body-composition measurement, and nutrition consultation to keep one's hard work from being undone by a carelessly eaten Pop-Tart-flavored Hot Pocket.
