Michigan's Adventure Boot Camp for Women

David Krainiak has been fit his whole life, participating in athletics at a young age, graduating from college with an exercise degree, and garnering 15 trainer certifications in his professional career. But the impetus to start a women's-only boot camp began before all that. It started with his grandmothers and his mother, all of whom he watched struggle to stay fit while dealing with their demanding lives. When starting Michigan's Adventure Boot Camp, he sought to create a workout environment that would have welcomed any of his matriarchs--an accessible, noncompetitive camp for women of all ages.

Each boot camp spans four weeks of exercise, with classes held five days a week, with students making sure to attend on three of those days. 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.
