Well, I see you have (0) fitness minutes ... what are you waiting for? Come on let's move it, there.
Welcome. Eat smart, move more, develop new habits, seek support. Those are the keys.
5 years ago, I started WW and in the first week I started to walk. Just walk. It exhausted me in just 10 minutes. But I kept at it. Within a year, the walks became runs, the runs became races. First 5k, then 10k, then a half-marathon, sprint triathlon, full marathon ... OK, the fulls weren't my distance, but I can now do a half every week.
And I lost 90 pounds.
Motivated yet? You don't have to become a runner. It happened by accident for me. But you do need to move. Bike, swim, do not neglect strength training, sports. Just move it.
