For the past month I have been doing 2 workout programs at the same time. I started T25 from the top (just completed the Alpha round). I am also doing the 21 Day Fix workouts, which have become a favorite because I get to combine weights and cardio!!! My goal is 2 25/30 minute workouts each day. However, I don't always have time for both. I do get at least 1 workout in each day . Anyway, after a month of my hybrid program, I am really pleased with my arm and shoulder definition! I also have some great definition in my back! Love these programs!!
