I had a total hip replacement in 2007, and with a bit of some stenosis in my lumbar spine, I had noticed that my balance was a bit off, and I had weakness in several areas. The GYF workouts have truly drawn attention to where my strength needs to be. In just a few months, I've been able to show significant improvement...like standing on one leg to put my pants on, instead of holding on to something. I'm amazed at how well I had compensated for these weaknesses. I live on the third floor, and have stairs every day, bringing groceries, boxes of cat supplies, bottled water, up to my apartment. I'm feeling soooo much stronger, and know that a routine of daily exercise is so very important. Thank you GYF family for being there for me, and so many others. I will continue to sing your praises, and declare that everyone must "Keep it Moving!"Five Stars!!!!!
