Great fun class! Lots of energy!

Fernanda, September 22, 2019

This class is a great workout (sweat and was sore afterwards), however you either have to have dance experience or be really comfortable and laid back to enjoy the class. The pace of moves is really fast and you just bounce around the whole time

Super fun class!!

Ela, March 21, 2018

The instructor was full of energy a great vibe and easy group, tricky to navigate BSC Lab. I prefer spin/bootcamp/weight type classes but definitely would recommend for anyone who likes to dance/shake their bum!

Kira, March 20, 2018

They switch moves pretty quick so its hard to keep track of whats happening, especially with the loud music. You feel lost a lot of the time

Alfe, January 20, 2018

Great energy, fun class! Like an amped up zumba class but with sexier and harder moves!

Rosie, January 16, 2018

I loved 305!! The teacher was awesome and the class was a total blast!! I really like getting workout classes on nift. I am a classpass user and 305 is not an option on their platform, so I really appreciated getting to do something a little different!! I loved the class so much that I bought a package afterwards and have been going/bringing friends along. Really loved this nift.

Fun class!
