You've got a long ways to go, but you're on the right track. Work out until it's a serious challenge to get up a flight of stairs, then rest. Two-a-days are not a bad idea, but don't overdo it. Take one day off each week, at a minimum.

And just keep at it. You'll feel pretty weak at first, but over time, you'll see the change. Give it at least 2 weeks before you pass any judgement. A month might be more realistic, and we're not talking serious change in a month, just the beginnings of it.
