I'm 23 years old (150 lbs, 5'-7") and in pretty bad physical shape.
I've been smoking/drinking for the past 7 years and also been living a very sedentary lifestyle. I spend about 8 hours on the computer at work and then 4-5 more at home. That's pretty much what I do 90% of the time.
I've made the decision tonight to quit smoking and get into shape. My posture is poor, I feel tired most of the time, and my endurance & strength are at an all time low.
How you would recommend I go about this given my history? (I really want to focus on cardiovascular health & posture).
Also is anything (exercise/diet related) proven to help outdo some of the damage from smoking?
