I have taken a handful of classes of various types here. I have learned so much from the Physical Therapy experts that work here. You wont get this at any other studio!! After having low back fusion surgery I wasnt only nervous but I was scared to return to any form of exercise! I was a runner, kickboxer, HIIT lover, and boot-camper type of exerciser. But after surgery my body needed to learn a different type of exercise and achieve the same vigorous intensity that I was used to. Dr. Christine Romani-Rubi evaluated my weak spots, gave me exercises I can do at home to strengthen and correct

I am part of a fitness club at Pitt and we work with this studio often. The instructors are amazing, kind, and clearly passionate about what they do. They are able to give fantastic pilates workouts to 80+ girls in one session and leave everyone smiling. The studio itself is beautiful with many different class options (My favorite being bounce). You will not regret taking a visit to PHI Pilates.

PHI Makes Fitness FUN! I started taking Bounce (mini trampoline/rebounder) class here about a year+ ago & absolutely love it. It's truly like recess for adults! The instructors are very friendly and super high energy. The facility is large with big windows - bright & airy! Best of all this studio focuses on proper form & alignment, so regardless of what class you are taking (a fitness class, Pilates, Yoga, etc.) you will always be working on ways to stretch & strengthen your body without the worry of getting hurt.

PHI is my favorite pilates studio! I am so impressed by the high level of knowledge that the staff has and their ability to make small postural adjustments that have a huge impact on relieving pain or tightness. I absolutely love going to PHI pilates every week!
