I tried the free week at CorePower with a friend. I was particularly interested in the CSX (Core Strength X) classes, which were advertised on the website as “low heat,” though it wasn’t clear what temperature that actually meant.
The first class I took was 80°, the second was 92°, and the third was even hotter- you could clearly feel the heat actively running particularly in the third class. I’m genuinely unsure why the rooms were heated, since that’s not what I thought I was signing up for.
I also found it extremely difficult to book classes. I was lucky to get into three sessions, but most other classes I wanted either didn’t fit my schedule or were already full. Many classes are scheduled during the day, which isn’t practical for those who work in person 9–5. When I did find classes that worked for me, I was often waitlisted at #8 or higher, making it very unlikely I’d get in.
I should also mention that most classes Corepower offers are heated, which I personally don’t prefer. That’s partly my mistake for not researching more thoroughly before starting the free trial, but based on these experiences, I don’t anticipate returning to CorePower.

I’ve had a very positive experience at CorePower Yoga – Walnut Street, and after trying three other yoga studios in downtown Philadelphia, this is the one I ultimately chose.
Pros:
Numerous classes throughout the day.
Clean locker rooms with showers (a must for me since I walk to and from home).
High-intensity workouts with upbeat, contemporary music.
Free one-week trial with no commitment.
Unlimited memberships include a few buddy passes.
CorePower is ideal if you’re looking for a more Americanized version of hot yoga—which I personally prefer. The classes feel like a fusion of yoga, Pilates, and cardio. They’re fast-paced, energetic, and very much a workout rather than a traditional or spiritual yoga practice. That said, I still find active movement to be quite meditative, even if it’s not quiet or subdued. If you’re seeking incense, silence, and a traditional format, this probably isn’t the studio for you.
I’ve been going for a little over three weeks now and have yet to have a bad instructor—every class has been solid. Most instructors bring what I’d describe as a warm, encouraging, “gentle-but-motivating” style: pushing you to challenge yourself while also creating a safe, nurturing environment where it’s completely okay to rest or modify.
The studio itself is darker, which I really like—it helps with focus and minimizes self-consciousness. For anyone worried about body image: this has not been an issue at all. I’ve seen people of all shapes, sizes, ages, genders, and ethnic backgrounds. The vibe is inclusive and non-judgmental (definitely not Dodgeball’s Globo Gym).
One honest note: this is more of a corporate model than a community-driven, boutique studio, and that’s noticeable. I’m fairly reserved, and while very outgoing people could absolutely form friendships here, if you’re hoping for small classes, familiar faces, or instructors who know your name, this may not be the right fit. I haven’t noticed much of a built-in community, and I rarely see the same students twice. Personally, that doesn’t bother me, but it may matter to some.
If your primary goal is to work out, sweat, and get in and out efficiently, this is a great option. Evening classes do get very packed—some even fill completely with waitlists—so sign up early. Be aware there’s a $15 late cancellation fee if you cancel within two hours, and I recommend arriving early to secure a mat spot; coming in five minutes before class can be stressful.
For management: One valid critique is that the music can occasionally be so loud that verbal cues are impossible to hear. Some studios address this by providing instructors with lightweight headset microphones, which could be worth considering so cues remain clear even with higher music volume.
Regarding customer complaints about the temperature: each class description clearly indicates the heat level in advance. If you prefer a less heated experience, choosing low–medium heat or non-heated classes is the best option. Taking a moment to review class descriptions before booking can help set appropriate expectations.
Overall, if you’re looking for a high-energy, musically driven, inclusive, workout-focused yoga studio with excellent instructors and good amenities, CorePower checks all the boxes.
