Yoga challenges the mind and body without the violence and hurt feelings of full-contact chess. Steer clear of overaggressive pawns with today's Groupon: for $25, you get five yoga classes at BKS Iyengar Yoga Center of Honolulu (up to a $75 value).

Co-directors Shelley Choy and Ray Madigan rely upon their training from the Iyengar Institute in India and their staff of instructors to help students forge sturdy mind-body connections. The studio's robust schedule accommodates a variety of ages and skill levels with classes that embrace the techniques and philosophies of Iyengar yoga. Basic sessions gradually introduce sequences of precisely aligned poses, and Intermediate sessions incorporate inversions and shot-put throws to create a more physically demanding practice. Beckoning youthful yogis age 5–11, Yoga for Kids invigorates tykes with a dynamic session that incorporates yoga postures, interactive games, storytelling, and geography flash cards for the aspiring yogis. Iyengar yoga's graceful asanas hone muscular stamina and flexibility over time, focusing thoughts inward with rigorous physical alignment and controlled-breathing exercises that foster centered mind-body connections. Intent on molding limbs into constellation-worthy orientations, the studio supplies attendees with mats as well as posture-aiding props. Class size is limited, so Groupon customers are asked to arrive early to ensure a spot.
