Unlike friends playing hide-and-seek, muscles can’t be coaxed from their hiding spot by loudly yelling that you have free ice cream. Beckon bashful biceps with today’s Groupon: for $19, you get a gym-membership package at Prairie Life Fitness (up to a $135 value). This Groupon is valid on Q Street, South 132nd Street, and at the intersection of South 31st Street and Farnam Street. The package includes:

• A one-month gym membership (up to an $80 value)
• One personal-trainer session or one group Pilates-reformer class (a $55 value)<p>

Prairie Life Fitness manages muscle maintenance with a team of knowledgeable trainers, personalized workout regimens, and sleek exercise machinery in an upscale, 60,000-square-foot facility. A one-month membership gives fitness freestylers autonomy to explore the latest cardio machines and strength equipment to build a regimen that best fits their needs and preferences. During the one-hour personal-fitness session, an expert trainer carefully conditions the body to ensure that newcomers know to lift with their legs and not someone else’s. In the Pilates-reformer session, groups of four to seven patrons harness the low-impact rolling motions of the reformer machine to gently yet firmly fortify their core and lengthen muscles.

After land-based laps, fiddle-fit specimens can relax by the pool, indulge in a whirlpool dip, or lounge in the steam room⎯or reup energy with a fruit smoothie (not included with this Groupon) from the gym’s café after a pickup game of full-court basketball.

Although Prairie Life Fitness sometimes features a discounted price online, this Groupon still offers the best deal available.
