Way out of shape...heart check 1st ?

Seeing a doctor is a good idea. I know some fitness centers offer free assessment when you join/obtain membership with them.

I would start light so you won't exhaust yourself. For myself I also do some sort of self-reward to keep the motivation going. I wouldn't go based on the amount of weight lost because it's putting too much stress at the beginning, I would go based on how many times a week you work out.
