It may seem counterintuitive to some, but Affirm Fitness’s head fitness trainer, Lauren Leitner, also owns a biscotti-making business. Of course, all of the desserts she doles out are low in fat, making them tasty complements to the healthy lifestyle that she hopes to impart upon her students at Affirm Fitness. There, she and fellow trainers lead exercisers of all stripes through boot camps that are either traditional or tailored to new moms. Cardio-and-sculpt boot camp shows exercisers how to have fun as they transition between drills in agility, interval training, and body-weight resistance. In baby-friendly Bootie Camp, participants push strollers a little bit faster than usual for a cardio workout that allows them to spend time with little ones while they improve themselves. Moms can even spend a little time sculpting muscles with hand weights or by lifting diaper bags filled with bricks. Affirm Fitness’s class schedule also includes dance-inspired Zumba cardio workouts, relaxing yoga, and TRX suspension training.
