"One of my Body Back goals was to fit into my clothes better. Well, today, I went suit shopping for my big D.C. trip and actually felt good instead of disappointed." - Allison, Body Back client. Over the course of one eight week Body Back Transformation Session, Alison lost 4 inches, increased her timed burpee total from 38 to 64, more than doubled her timed plank, and increased every other strength and endurance assessment significantly! We are so proud of her accomplishments and she is rocking' that suit! Are you interested in Body Back? We have 2 sessions starting this weeks!
