The most secretive body parts are muscles, which hide behind layers of skin and appear only occasionally to help lift cars off trapped kittens. Flex your biceps in the absence of a cat emergency with today's Groupon: for $29 you get a month of gym membership and tanning, and two personal training sessions at Powerflex Gym on Eubank Boulevard (a $125 value). This Groupon is only valid for Albuquerque residents.

Powerflex Gym’s workout machines and tanning bulbs burn 24 hours a day, seven days a week. Membership includes access to a spread of cardio offerings including treadmills, ellipticals, and stationary bikes that challenge hearts to power your hard-working fitness factory. Sculpt muscles into the shape of a lithe chipmunk or a useful dish to store your keys via the gym’s strength training equipment, including weight machines and a brigade of free weights. Personal training sessions provide guidance from one of Powerflex’s degreed professional trainers, who happily help maximize impact from equipment, set exercising goals, and craft fitness strategies with paste and chains of amino acids. After improving subterranean aesthetics, add the finishing touches to your muscle covers with an eight to 10-minute session in a European tanning bed.

Members can take advantage of many Powerflex perks, including locker room and shower facilities and a complimentary gym orientation session. Flexors enjoy free Sirius satellite radio on many machines, preventing the need to distract themselves by calculating calories burnt in an hour of mustache growing. Additionally, those in need of fitness accoutrements can turn to Powerflex’s pro shop, which vends a workout gear and nutritional products (not included in the value of this Groupon).
