Why You Should Go: Whether you're slumped over your laptop or hunched above the final book in The Hunger Games trilogy, there is much to malign about your alignment. Straighten up while sculpting long, lean, dancer-like muscles at Posture Perfect Pilates in the South Loop.

What to Choose:

• $59 for a crash course of three one-on-one Pilates sessions ($99 value)
• $45 for five Pilates mat classes ($75 value)

Why You'll Love It: No matter if you’re lean and limber or stiff as a board, these classes will give you a hard-core workout in the encouraging atmosphere of a small group (no more than 10 students per class). Newbies can learn the ropes in three 30-minute one-on-one sessions, while old pros can opt for five 60-minute mat classes to refine their muscle-flexing techniques.

What You Should Know: PPP's classically trained instructors are extremely talented (and limber), with several possessing  former professional dancing experience. As they guide you through each stress-reducing, body-sculpting workout, they'll offer up unpretentious and encouraging instruction so you feel comfortable whether you're already rocking a six-pack, or haven't exercised in ages.
