Much like libraries, gyms arose in response to the need for self-improvement and the physical strain of dragging around personal book collections. Limber up with today's Groupon: for $22, you get a 30-day gym membership (up to $89 value) to GoodLife Fitness in Barrie.

GoodLife Fitness augments a squadron of strength training and cardiovascular equipment with a packed schedule of energizing and encouraging group fitness classes led by skilled instructors. Delve into a Body pump barbell class, challenging muscle groups to a series of squats, presses, lifts, and increasingly complicated origami designs, or fortify weary musculature by wielding light weights during a Newbody class. Workout warriors can also test their mettle in intense Body Combat classes, merging martial arts disciplines to fill students with the strength and endurance to dodge roving packs of ice cream trucks.

After a thorough workout, club amenities such as massage therapy, saunas, and tanning beds imbue bodies with a refreshed glow. Additionally, GoodLife Fitness' childcare services give parents freedom to workout and tykes time to practice bench-pressing imaginary friends.
