It's been 8 years since I decided to get into better shape. My 73rd birthday is a few months away.
My advice, to anyone overweight, walk, not run to get your cardio. Unless you are put together really well, running distances, consistently, will likely show up with chronic pain in one of more joints. Sometimes you won't get the chronic pain dividend for a number of years. Once you have it, it becomes part of who you are.
Weightlifting has been a fountain of youth for me. Like many, I found it boring in when younger. This time around, it became enjoyable physical exertion that can be matched to your ability on that day. It will ABSOLUTELY make you stronger if you are consistent and actually challenge yourself. I'd advise that you spend your efforts on compound movements. I've settled on overhead presses, weighted pull ups, bench presses, back squats and trap bar deadlifts. If I was to add one, it would be some form of farmer's walk.
