$139 for Unlimited Five-Month Outdoor Boot Camp (Up to $379 Value)
Boot camp classes start April 2 and run through August 31, with several hour-long sessions per week meeting at Millennium Park, Lincoln Park, and Montrose Beach. Three outdoor classes meet each week, tightening cores and jumpstarting hearts with intense cardio. Guests can drop in on Ultimate Conditioning on Friday mornings, the 300-inspired Spartan Workout on Saturday mornings, and chisel silhouettes with hip-shaking Zumba classes Sunday at noon.
The certified and licensed instructors at ENRGi Fitness motivate fit-seekers, from newbies to seasoned athletes, during more than 130 classes and boot camps per week. The instructors lead high-intensity kettlebell boot camps, will-power-testing Warrior conditioning classes, and fun-focused Zumba sessions, accommodating patrons of all experience levels with modifications and large doses of positive reinforcement. During circuit training, exercisers whip hearts into a strength-gaining frenzy, and build upper-body power during rowing courses. After making use of the multi-room workout center—which includes a zen studio for bodywork and stretching sessions—guests can wash away sweat and caked-on synchronized-swimming makeup in brand-new showers.
