Michigan's Adventure Boot Camp, Chesterfield

Each boot camp spans four weeks of exercise, with classes held up to five days a week. Classes might meet indoors or out, depending on which of the nine locations a client chooses to attend, but the regimen of exercise remains the same. Trainers cook up new routines daily, which might include fitness kickboxing, jump-roping, obstacle courses, or sport yoga, in which the class plays a scrimmage using the first student who manages to contort themselves into the shape of a football.
