I really enjoyed the Cardio Core class! I haven't attended a fitness class in like a decade and I found this 30 min class to be a great way to get my heart pumping and get back into a fitness routine. The exercises kicked my butt, but they felt accessible and (for the most part) I was able to keep up with the pace. This class cycled between different workouts every 20-30 seconds, so it's great for folks who get bored doing the same thing for 30 minutes straight.
