Lots of variety and ingenuity in your workouts here. For something else to do with abs, there are saxon bends and landmines. Keep up the good work.
I can't imagine what it must be like to be 50# heavier. You would have to carry a duffle bag of food around with you wherever you went. It must cost big buys a small fortune to eat.
