It's hard work, but easy to follow with the trainer guiding you. Sean was great with guidance and correcting form at the Wicker Park location; And, I love Mia and her motivation at the Oldtown location.
The workout was incredible! It truly suits every fitness level, you get out of the workout what you put into it. The instructor Hakeem was incredibly helpful and didn't make me feel like I didn't know what I was doing since it was my first time. He walked through instructions prior to class. Really upbeat music and welcoming environment.
