Mighty Pilates was featured on 7x7 and Daily Candy. Nine Yelpers give five stars.

• Novices and buffs alike will no doubt leave sore after their energetic full-body circuit classes that incorporate Towers in addition to Reformer machines and fat-blasting cardio, all set to a hip soundtrack. And since they know you've got other things to do, they supply everything you need to get ready for shopping on Sacramento or dinner next door at Spruce. – Jaclyn Binder, 7x7
