I feel kinda silly posting what I am doing for exercise, but I figure some is better than none! I bought a gazelle machine and did 5 minutes so far today. I am doing 50 situps a day and can do 40 reps? what ever it is called on my ab scissor machine. I admit I have to take a break between them on the scissor machine, but I do 10 at a time. Will this help me lose weight more, or am I just wasting my time? I would really like to get my belly flatter. I have had both knees replaced and can't do any exercise that involves my knees on the floor or taking any pressure.
