re: Workout routine for severely out of shape 50 year old male

If truly severely out of shape . . .

Probably by walking and some easy stretching to start.. along with some push away's from the table. Beer likely needs to become more of a treat and not an every day acquaintance. Might help to keep track of your vital statistics by letting the heart rate and blood pressure track your initial progress. Little baby steps leading to a life style change. Too many go for broke and never reach where they want to be.
