Ok, so right now I am healing from surgery on my shoulder. I have full motion and am doing therapy 3 times a week. Arm feels great but I am not allowed to lift for another couple weeks. I was in the middle of doing Insanity and eating a low carb diet to drop the unwanted fat. I am not looking to build muscle again as of now, I want to lose the fat first and then start building some mass. My diet is in check and in almost 2 months of Insanity I dropped 44lbs =) But I still have a little ways to go. I have been trying to do the tabata training on the stationary bike, but even though it is extremely tiring and hard, I feel that 4 minutes just doesn't seem adequate enough to lose the rest of the fat. I can do anything except lifting weights or pushups with my shoulder. Can someone steer me in the right direction to a good workout routine that can help me shed the rest of my fat?
