I have been going to Amazing Yoga for years. I have been to both the Shadyside and South Side locations. I prefer Shadyside just because its easier to get to most of the time with traffic. Parking is tight but I can usually find a spot on a side street.
I really love their idea of hot yoga flow here. Most of the teachers are great but Lisa is my all time favorite. He classes are tough but totally worth it. The teachers used to not play music but I think they all have music now. I don't mind either way as long as I'm getting a good workout in.
I like that they have several classes a day to pick from so its easy to find something that will fit into your schedule.
They have a boutique that you can shop from as well before or after class.
Don't come late because they lock the doors.
