Aside from climbing out of rattlesnake-infested quicksand or posing for rattlesnake-infested watercolor portraits, few activities combine the focus and physicality seen in martial-arts training. Hone your rattlesnake-conquering skills with today’s Groupon: for $29, you get a 10-class pass to The Studio Martial Arts & Fitness in Granite Bay (a $140 value).

The Studio fosters fitness and makes martial-arts masters out of fledgling fighters. Instructors Jack Corrie (a seventh-degree senior master) and Amitis Pourarian (a sixth-degree master and former U.S. team member) coordinate and co-operate the body-fortifying center, contributing a combined 50 years of martial-arts experience. During a wide variety of classes, students learn to maneuver their metatarsals and middle ears in a menagerie of different workout methods designed to pump hearts and arms.

Thirteen weekly cardio-kickboxing sessions combust calories and galvanize muscle-guns, and Monday-morning circuit training gets to work defining muscular fibers. Students in tae kwon do classes of all levels build strength and discipline as they learn how to defeat an attacking horde of killer tomatoes with their bare hands. Yoga and Piloga classes cool down broiling calorie-burners with stretching and sun saluting designed to pacify the lactic-acid gods who rule the fate of postworkout muscles.
