High intensity cardio class with great balance of agility, strength And cardio. Wish the AC wasn’t on but small issue.
DIRTY 30 with Maryam
High intensity class that’s to the point. Feeling all kinds of sore the next day.
TABATA 30 with Maryam
Great class. Perfect 30 min tabata format. Get ready to work and sweat. Maryam is tough, but fair and motivating. Will definitely be coming back.
LEVEL 10 with Maryam
Decent class but not nearly as intense as described. 45 minutes would be better or increased intensity.
Love Skye, every class with her is always great!

I was expecting a 30 min row class but I was pleased with the class..Non stop..Great workout!
Great workout - interesting and challenging sequences, and included more footwork than other classes I’ve tried in the area. Will be back!

How to prepare

***First-timers please arrive 10 mins early to fill out waivers. No one permitted in after the start of class - NO EXCEPTIONS - it is disruptive to class so we thank you for understanding. No cell phones and please be nice to our turf and wipe your feet. Classes are extremely difficult and they are a studio that stresses form - please do not take it personally if you are corrected - just be willing to learn and work hard. Water, towels, hair ties and tampons provided. Changing room, bathroom and shower.
