Hi, I'm new to the forum and have learned a lot reading through the questions and answers. Can't think of a better place to get expert advice. I've decided to quit smoking after 2 years. I've always taken care of my health until I went through a rough divorce (an all-too-familiar story). I'm 43 years old and been active most of my life. My plan is to begin training seriously while at the same time stop smoking. I am 5'8" and 113 lbs. My goal is to increase muscle and become a little leaner. Like most people considering quitting smoking, I'm concerned about the weight gain that I've heard about. I eat clean already, and hope that the proper exercise formula will prevent an increase in fat. Can anyone recommend a training program? Has anyone quit smoking and not put on fat? I'm currently easing back into exercise by running 30 minutes 4 times/week. I'm convinced weight training is the key. Can anyone give me advice? Thanks for the help!
