Yoga is a much easier way to exercise both mind and body than testing Einstein's theory of relativity by racing a beam of light. Avoid a science-related sprain with today's Groupon to Floating Lotus Yoga Studio & Natural Healing Center in Mesa. Choose between the following options:

• For $15, you get 15 yoga classes (up to a $160 value).
• For $59, you get participation in the 60-day Cross-Tone challenge program from August 1 to September 30 (a $125 value).

Floating Lotus unites the power of acupuncture, natural healing techniques, chiropractic, and yoga into a studio of mind-and body-balancing bliss. A host of flexibility-enhancing classes takes place atop Floating Lotus’s 1,500 square-foot maple wood floor, ranging in intensity from advanced Ashtanga practice to slow-paced restorative flow. Beginners can enroll in the basics class, which instills the fundamental postures, breathing techniques, and Gumby idolatry that forms the backbone of the bendable art, as instructors emphasize proper alignment for student safety.

Alternatively, exercise enthusiasts can undertake Floating Lotus’ Cross-Tone challenge, a 60-day program designed to annihilate inches and pounds. Using a combination of cardio, strength, resistance, and interval training, Cross-Tone workouts put participants through vigorous routines designed to work the entire body. Classes meet Monday, Wednesday, and Friday at 6 a.m. from August 1 to September 30 for a total of 24 one-hour sessions or roughly half the amount of time it takes to shrink fat cells in the wash.

Though Floating Lotus Yoga Studio & Natural Healing Center sometimes features discounted prices online for yoga classes, this Groupon still offers the best deal available.
