Working out is No. 3 on the list of most popular daily activities in America, behind not working out and teaching dogs to swear. Spend your time wisely with today's Groupon: for $39, you get a one-month membership and a one-hour personal training session (a $169 value) at Equalize Fitness in Yonkers.

The body architects at Equalize Fitness believe that, like any good edifice, one’s corporeal home should be strong and safe, and are on a mission to get mortal vessels of all ages and fitness levels one step closer to this ideal. During an initial one-hour fitness assessment and personal training session (an $80 value), a personal trainer will give every muscle in an individual’s body a strenuous multiple-choice exam and then assign a prescriptive course of studies to muscle groups that need to improve their grades. Following this diagnostic confabulation, cardiovascular systems can thump their way over to the cycling studio or to group fitness options such as Butts and Guts, Afro-Caribbean dance, Zumba, or Hatha yoga.

For one month, Groupon holders also get unlimited time with the free weights, strength training equipment, and cardio equipment in the studio (an $89 value), helping them to achieve the geometrical shape of their choice and build biceps capable of winning arm-wrestling marathons. An on-site juice bar helps healthfully slake post-workout thirst.
