I could not have more love for PB. The concept is genius, and I love how it is geared towards women and the parts we want to tone: abs, butt, thighs, arms. The class is fast paced and the instructors are fantastic. I really like Jasmin at the Scottsdale location, she physically corrects form and explains technique well. Before I went to a PB class, I thought I was in good shape- I run half marathons, work out a few times a week- but it is a HARD workout. Like, HAAARRRDD. I never thought using such small movements and hardly any weight could tone and burn so much (and leave you so sore). It's expensive but definitely something that's a treat, try it out!
