I think it amazing that you are so positive. 2 pounds a week is doable. IMHO I hope you can consider the odd week that you may lose nothing.
The mental aspect of losing weight is the biggest. You obviously are motivated and I love the fact that the first person you are doing this for is yourself. You are right, your family needs the best person you can be.
I'm not sure if you have a variety of weights for your weightlifting but you can also use your own body weight for a great workout.
You sound younger as you don't list any health problems. Us older folk always manage to slip it in somewhere.
I wish you everything you wish for yourself. Post often, this is an awesome group. Plus I've never seen the dual bike before.
