Realized a couple weeks ago I'm sneaking up on 40, and although I'm a lot fitter than I was several years ago, I have a long way to go still. Last year I climbed Mt Rainier, currently can run a 2:00 half marathon, and would like to do so again, and bigger mountains, with more energy in reserve this time.
Currently lifting weights 5-6 days a week and doing 30-60 minutes a day if cardio, along with strict carb control and intermittent fasting. I'm not running any big miles since my knees don't like my fat ass doing more than ~25 miles a week, but the weights have started to make a real difference over the last couple weeks already.
