That app is awesome, I just downloaded it. I am having bypass hopefully in the next few months. I lost over 100 lbs naturally with a trainer and working out but have a congenital heart defect so I can't do cardio but I love to lift. My weight is starting to creep up, so my cardio finally said I can have surgery since I have maintained a 60+ weight loss for a few years, and a few heart surgeries. I am so excited about that app, I have ALOT of restrictions due to my heart, and surgeries. I love that it shows you the way to also do exercises.
