New to any type of work out routine... Help!
Gave up Smoking 7weeks ago. I have been walking daily for 30 days now. I joined the gym last week and have yet to go. I REALLY enjoy my daily walk in the park and am up to 3 miles per day. I want to start "couch to 5k" today. I have program downloaded to smart phone. What I want to know is what is a good switch up from gym…
