AWESOME! I started in May and didn't come back for a while due to some high stress events in life, but once I came back, I loved it! I haven't experienced as much weight loss as I was hoping, but on a non-scale victory, I can defintitely FEEL all the muscle I've gained! I'm now able to do some real push-ups without being on my knees! All of the instructors are fabulous and SO willing to help with any questions I may have. Love love love ILKB!
