Don’t let the term “high-intensity” faze you. Most of these boot camps welcome everyone from couch spuds to fitness studs. Perhaps not suprisingly, Lincoln Park is this trend’s epicenter. Ten-hut!

Lincoln Park

BeachFit

North Avenue Beach, 1600 N. Lake Shore Dr.; meet under the black Special Forces flag

Exercise physiologist and trainer David Hardin’s 30-person sessions focus as much on improving core strength and mobility—and avoiding injury—as on toning muscles and torching calories. Bonus: There’s zero running involved. $10 a class. dhfit.com

Bulldog Bootcamp

Lincoln Park; meet on Cannon Drive between Fullerton Avenue and Diversey Parkway

These 60-minute classes are as close to a real boot camp as you can get without enlisting. Instructor Suzanne Friday (whom you’ll refer to as Sergeant Friday) will call you out by name if you slack off. Expect barked-out commands to sprint, squat, and army-crawl. Four-week sessions: $195 for five days a week or $135 for three days a week. bulldogbootcamp.com

Fit Lincoln Park’s Fit Bootcamp

Oz Park, 2021 N. Burling St.; meet near the corner of Webster Avenue and Orchard Street

Take one of this studio’s classes, taught by co-owner Bojan Jocic, and you won’t stop for 60 minutes. (Literally: Planks are your “rest” between circuits of hill climbers, pushups, and the other exercises.) Workouts are adapted to each group’s fitness level. $10 drop-in rate or $150 for three classes a week for eight weeks. fitlincolnpark.com

Logan Square

Paramount PT Boot Camp

Palmer Square Park, 2200 N. Kedzie Ave.; meet at the corner of Palmer Street and Humboldt Boulevard

Owner Alex Nsiah-Kumi’s program feels like personal training: He caps each class at 10 people. You’ll use kettlebells and other equipment, which you’ll incorporate with body-weight exercises and running. Expect to work your butt off. (This high intensity camp is not advised for beginners.) Mondays and Wednesdays at 6 p.m.; Saturdays at 9 a.m. $199 for a six-week session. paramountpersonaltraining.com

The Loop

Fit Results Bootcamp

Grant Park; meet at the corner of Ninth Street and Michigan Avenue

Trainer and ironman Luis Centeno leads high-intensity, interval-based workouts: a seemingly endless mix of novel moves—he brings giant ropes and other gear to the park—along with sprints and body-weight exercises done in short spurts. Plus, this outdoor camp pumps you up with music. $45 for a four-week session. fitresults.net
