The workout itself is intense and difficult. Keigan is my favorite teach though. He has the best music! No other studio is the same. Also everyone is friendly (other customers, too) and the place is very clean.
It was definitely a drenched in sweat, muscles turn to j-e-l-l-o workout! BUT it was FUN!!! The folks attending are super encouraging! The trainers really watch to help you have the correct form and max out your potential. They are super focused on YOU doing YOUR best.
I signed up for 2 classes a week...to get started. (I can easily see where after a couple weeks I may try to increase.)
It's challenging but fun. I like that the workouts vary so much so I don't get bored. In the year that I have been going, I've had to work around a shoulder injury (which healed) and a knee injury (currently), but I'm still able to complete the entire workout with a little assistance from the trainers in coming up with modifications that are safe for my body. It's a competitive and encouraging environment and definitely the best workout I've found.
