Exercising has come a long way from outrunning a lion until it reaches the point of exhaustion so its sleeping carcass could be bench- pressed and shot-putted. Build muscle using nonliving weights with today's Groupon: for $39, you get a one-month membership (a $100 value) and three personal-training sessions (an $80 value each) at Gold's Gym (a $340 total value).

Gold's Gym began more than 45 years ago and today features an impressive array of next-generation fitness gadgets, a results-oriented focus, and clean facilities that span three levels and 40,000 square feet. With today's deal, one of Gold's Gym's certified personal trainers will work with clients to design a personalized fitness regimen. To ensure the most rippling results, all three personal-training sessions take place within the first two weeks of the one-month membership. Then neophyte iron-workers can follow up with regular visits to the gym, where they can hop on a cardio machine, pump up in a controlled manner on strength-training machines, tighten up in the abdominal and functional stretching area, or stick with lifting huge, heavy pieces of metal and commercial chest freezers.
