I do 3-4 times a week. You just have to keep at it, and one day you can't live without it. I just turned 40 and I lift. I hold my own at pool parties in Vegas. I'm in better shape now than I was when I was 20. If I am stressed, or tired, or don't feel great - I go to the gym and feel like a million bucks. One day, it will absolutely tip the balance. Just keep at it. The results are addicting
