Chances are the unfriendly waters of Lake Michigan aren’t calling your name. Luckily, you can achieve a surf workout on dry land—The Langham’s new surf-inspired class encourages locals and hotel guests to hang ten on their outdoor plaza overlooking the Chicago River. You’ll score a core-burning workout that’s a lot less mundane than the crunch sets you’re used to. Expect an array of body-toning exercises such as yoga balancing, cardio bursts, squats, and on-board jump-ups. Classes are offered Tuesdays and Thursdays at 5:30 p.m., Saturdays at 10 a.m. and 11:30 a.m., and Sundays at 10:30 a.m. from July 5 until August 30. $35; 330 N. Wabash Ave., 312-923-7650

If your barre-obsessed body is so used to hip tucks and plié squats that you no longer feel the burn, it’s time to take it up a notch. Enter: Pure Barre’s Platform workout. The barre studio, which has seven locations around the city, offers its newest class at a faster pace than its traditional sessions. With a platform set in front of the bar, you’ll tap into more dynamic movements plus high-intensity interval sets to get your heart rate way up. The instructors encourage big movements, so while you may feel silly, you’ll know there was a reason for it when your soreness returns the next day. $25; 319 E. Ontario St., 312-914-6553
Opting for the elliptical over the treadmill is a smart move if you’re trying to save your joints—but being a slave to the machine can become stale. Try Sproing HIIT, a 45-minute Tabata-style class, instead. You’ll be running, squatting, and jumping from the cushy surface of the Sproing Trainer, which replicates a sandy beach jog... but with 50 percent less stress on your knees. $30; 1652 N. Wells St., 312-226-2786
