Student Testimonials
The Grandlake instructors are welcoming and So friendly! I especially appreciate how clean the space is.
Sue was a great instructor. She was clear, and really helps keep you on track and doing the movements correctly and keeping the right breath cadence. Her classes are paced well and are challenging.
The instructors, studio cleanliness, welcoming environment, variety, music
Favorite studio in the East Bay! I was visiting the area and stopped by Grand Lake, Rockridge, and West Berkeley -- and Grand Lake was my favorite space AND favorite instructor. Killer class. Thank you!
First and foremost the studio has a great vibe. It is clean and spacious. As for the classes, I’ve so far taken three classes and I loved everything about them. The instructors make sure to modify the exercises and that alone made me feel comfortable and confident.
The instructors at Grand lake are great
I really like yoga sculpt
I really enjoyed attending Asha’s class. She is an excellent instructor and had great pace and I really appreciate her energy. Thank you!
I love that your studios offer a free weekly class. It allows us to try out different teacher styles.
Great teachers and variety in workout
Love the instructors
good class
Everything! Especially the instructors who create both great yoga classes and a strong sense of community.
Loved my afternoon yoga sesh with Sean - he's HILARIOUS and his levity and humor helps with his longer static poses. I'm in awe on how much stronger I feel after that class. I absolutely love his Phantom of the Opera yoga combining storytelling and yoga flow. I'm on a health journey and CPY is supporting it.
Heartily clapping for all the yoga teachers at CPY!
Instructors are fully committed and friendly
The instructor was amazing! I have never had that good of a flow before. Plus, the studio was super clean and inviting.
Highly skilled instructor; attentive to class participants, introducing varied options, walking around to correct some of attendees movements and most of all excellent music selection….
studio is clean, easy to access and Kelsey is a great instructor!
I've been looking for a great hot yoga since spot post COVID and this did not disappoint. You will sweat, work, and feel great after. I'll definitely be going regularly. This class was great because it focused on balance, something I am still lacking since a ankle and leg break. All different levels of folks were there and I felt welcomed being one of the least advanced. Super clean studio as well. Bring a towel and water, you will need it.
First of all, all my Grand Lake and Rockridge classes have been just MARVELOUS (heart eyes)! I can never decide which classes to take between these two locations. I have to go with convenience with time it's being offered and the length (LOVING those 75min classes)!
Wishing there were more 1.5 flow & HPF classes offered in the PM.
Another scheduling plus would be offering more Core Restore in the PM! I would most definitely double up and take back-to-back classes.
Jojo was great. enjoyed the energetic yoga 2 class
I think Olga is one of the best yoga instructors I’ve had in the last 20 years of practice. I met her through her classes in Rockridge and followed her over to Grand Lakes. I love the studio atmosphere at both locations.
First, the hour went by really quickly in Olga’s class Second, she had us do fundamental moves with smooth transitions that made the workout ergonomic and safe for my body, which I really appreciated. I also felt like I was in a very professional class where my technique was gently being improved. I’ve been looking for a C2 course just like this.
It's very welcoming and there is generous locker room space.
I haven’t practiced yoga in 7 or 8 years. This past Sunday I was invited to join a hot yoga class with a sound bath that followed. It was so healing! 10 minutes into movement, I could already feel an emotional release welling up from within. The instructor was easy to follow, and I felt immediately at ease within the space. Wearing glasses while doing hot yoga is not the easiest combo, but well worth the ability to participate in this. Thank you so much!
Facility is very clean, parking is easy and the staff are warm, friendly, accepting and encouraging. I'd like to give a shout out to Grace, Micheal and Miles. They all have very different styles of teaching and each one brings professionalism, positive energy and challenge !
It is very welcoming, lotsa classes, and has great accommodations.
Grace is the best!
Ashley is the best instructor I've had at corepower. I've taken classes in NY & all around the bay. She is by far the best. She comes to class prepared to give us an intense workout and incorporates advanced moves that I've never tried before. 100/10
I really enjoyed the yoga instructor. She was very sweet and cognizant to my needs for my first experience. She went above and beyond to make sure I had a great first experience and feel comfortable.

Variety of classes – from beginner-friendly flow to challenging sculpt classes with weights.
