Joseph Pilates invented his world-famous toning and flexing techniques to counter the constant taunts and teases of Slinkies, weasels, and the holier-than-thou giant African millipede. Safeguard your mind from the sin of bendy envy with today's Groupon: for $36, you get four Pilates mat classes (a $72 value) at Articulations Pilates Studio in Riverside. Beginner mat classes are held every Monday from 6 p.m. to 7 p.m., and intermediate classes every Tuesday from 6 p.m. to 7 p.m.

Unlike Rube Pilates-Goldberg classes—which use comically complicated contraptions to help tone, stretch, and flex muscles—Articulations' mat classes teach the fundamentals of Pilates using only an exercise mat, Pilates positions, and the freedom of the open road. Pilates's focus on constant motion and smooth, graceful transitions between exercises produces a lot of benefits—increasing overall strength and endurance (especially in the core muscles), improving posture, and keeping the body aligned.

Articulations' instructors maintain small-class formats to preserve the serene environment that their small-group format fosters. The studio's soothing sage and earth tones reinforce the tranquil atmosphere, making Articulations Pilates Studio a sanctuary for regaining your peace of mind as you flex, pose, and stretch your muscles to beneficial exhaustion.
