Student Testimonials
Great workout. The instructor was very friendly for my first time
I love this studio at Nob Hill and Berkeley-West and all the teachers that I have had. Most recently, it was Laura and Ms. Walker at the Nob Hill location and Ethan (?) at Berkeley-West. I like the flow of their practice, the instruction they provide, and the positive energy they charge the class with.
Love the classes and instructors. I always feel great after my classes. My only critique is that the classes are always uncomfortably full with people - we’re always mat to mat. Sometimes not having enough space for weights or to have to stagger to do the movements. Corepower could be a bit mindful about spacing and making sure we’re comfortable for the hour session.
Class times, the good workout and the community
Great instructors and really clean place! Lots of time slots available
Great studio
Amazing class! Hope is a great instructor and I loved every song on her playlist. Great challenging flow with a nice water leak ceiling backdrop that actually helped me persevere and flow through her Sun B+ . Also when you’re flowing next to bestie it’s like a free moving artwork show next to you! I AM DONE!!!

I like that there are plenty of times to attend a class, so missing is not an excuse. Besides, I like the music.
Demarcus’s class was amazing! I felt like a brand new person leaving my sculpt class and ready to take on the day!!!
The ease of use, the accessibility at different times of day, and the great teachers. We especially love Deron, Mireia, and Heather.
More C3 classes please!
The instructors are amazing and always bring their best self to classes consistently. I like that the instructor schedules are consistent so if I like someone’s style I can come at that same time every week and have that routine.
Would be nice if SUB teachers would be listed the day before, and not in the last second.
great early class, wasnt too crowded and the teacher did fantastic!
Good instructors, flow, class variety, near bus stop
We were visiting from L.A, and when we travel, we always like to hit up a local Core Power. We have yet to have a bad experience, and this location didn't disappoint at all. It was an excellent class from the instructor to the music to her combinations. Thank you!
Hannah is an exceptional teacher! She brought positive energy and enthusiasm to the class which helped me start my weekend off right.
The instructor was so difficult omg my legs & arms are still hurting this feels so great.
The teacher was great- that was the most fun class I’ve taken at core power
Did a double with Chris F at 12 and Alison U at 5:30. Both incredibly skilled tenured instructors originally from Core Power down in South Bay. This will probably be my new Thursday schedule moving forward.
I personally think both need a 4:30, 5:00, 5:30, or 6:00 pm section.
The teachers at Nob Hill are super friendly and welcoming and they always keep the flows interesting and engaging. As a fairweather Yoga practitioner, I love that I can drop in once or twice a month to get a good sweat and work on my flexibility without feeling pressured to change my practice.
I adore this studio and most of the teachers here (Shannon, Hannah, Ashle, etc.) However, the lack of wipes lately has been crazy. I also feel like the cleanliness has gone down? Did y'all get rid of professional cleaning staff.
Emma was fantastic and was very motivational and had a very creative fun sequence!!
Wonderful instructor, great workout

Welcoming community in my neighborhood. They switch up the flows often and I always feel great after.
