DIRTY 30 with Skye
Good workout for 30 mins. Great for beginners.
HIIT 30 with Amanda
I really like fast (in terms of length of workout) HIITs, and this was just right! Amanda Jane is a great teacher, very motivating, and friendly. She is also very good at teaching form and was always on the lookout for proper alignment throughout class. I’m hoping to make this one a regular.
COURSE X with Michael
Super challenging but a very effective workout! Michael is very attentive to form and technique.
CORE 30 with Skye
Amazing class! Skye has a don’t quit attitude!
HIIT XT with Maryam
Great workout!! I almost died. Too many people and the space is small.
BODY MECHANICS with Ryan
Challenging and dynamic. I wish the strength were a bit harder, but the cardio made up for it
BODY MECHANICS with Ryan
Maryam and Ryan are so motivating and make sure your form is correct!!! Great class!
LEVEL 10 with Michael
Awesome, fast paced class. Really good teacher, gives good adjustments and modifications. For only 30 minutes, you leave feeling beat.
HIIT XT with Michael
Super intense but good! Highly recommend if you’re athletic/active.
HIIT XT with Michael
Very good class! Everyone is very supportive and Michael was great- he clearly explained what was to be done, he was motivational, and he doesn’t hesitate to correct your form. It seems like there are a lot of regulars in the class- which is good since they know what they are doing so you can follow along easier if you are new. I wouldn’t go to the class if you don’t work out regularly- everyone is pretty intense and it’s definitely not easy.
Response from the studio:
We loved having you in class! Thank you for working so hard - see you soon.
