Each summer when the temperature is just right, Chicagoans poke their heads out of hiding to realize that summer truly has arrived. From that point forward, it becomes a pastime of windy-city-dwellers to find ways to do absolutely everything outdoors.

Drinking, eating, socializing, listening to music – but the greatest of all of these is fitness. As soon as the bathrooms unlock and the water fountains turn on, the Lakeshore path bustles with the action of – and sometimes competition between – bikers and runners.

But outside of the lakeshore path, studios and gyms find ways to keep you sweating, even when the idea of going inside can feel like torture. Here are a few must-do workouts to occupy those warm summer days.

Surfset at the Langham

Where: The Langham Hotel, 330 North Wabash Avenue

When: Tuesdays at 5:30 pm; Thursdays at 5:30 pm; Saturdays at 10 am and 11:30 am; and Sundays at 10:30 am. This class offering starts July 5 and goes through August 30

How do you sign up: Call the hotel’s Chuan Spa at 312-923-7650 or email [email protected]

What can you expect: Surfset is the workout that you may remember from Shark Tank. Using the idea of a surfboard and it’s intrinsic instability, you’ll do some motions you’re used to and some that are more familiar to those who surf. We tried this class format indoors and we’ve been addicted ever since. In your bare feet, get ready for a heart-racing, muscle building workout that will build balance and strength all at once.

Sweat at Joy District

Where: The rooftop at Joy District, 112 W Hubbard Street

When: Saturdays at 9:30 am

How do you sign up: Sign up like a regular class here for $25 for a drop-in. Various other class packs bring this price down.

What can you expect: Our friends at SWEAT are taking their signature workouts out of the studio, away from the treadmills and into the sun at Joy District for the summer. Expect a hearth-pumping Saturday workout with convenient access to the boozy brunches of Hubbard Street afterwards.

Studio Three Rooftop yoga at Joy District
