I've been working out every day for well over a year and haven't found a single workout that I haven't enjoyed. I'll admit that some of the workouts are still a little challenging but I don't (and WON'T!) give up. I look forward to working out every morning which is something I've never done in the past. My stamina and balance have improved beyond measure. My surgically repaired shoulder feels better than it's felt in years. Even the doctor is amazed. Thank you Deron!!!
