OMG Wiix, 5 flights of stairs! God bless you! I don't know how you do it!

Bobby, everyone is different. I couldn't walk 3 city blocks. I know that for certain tho, so I would never attempt to do it.

I think 3 minutes on the bike is good! And reasonable given your level of fatigue, your age, and the fact that you have physical limitations now from the stroke. The 10 minutes they had you doing at PT on the bike (and then more exercises!) was WAY too much... their eval and care plan were really off the mark, and you suffered for it

I think that you WILL do well with regular exercise like that if you don't push yourself too hard when you do go out or exert yourself in other ways
