So are other folks happy with their health and fitness? Unhappy? Do you yo-yo or are you pretty steady? Do you have specific health or fitness goals? And do you prioritize this, or does it take a back seat to other "life" elements?
I'd love to hear other peoples' situations and the obstacles you've faced.
How much time do you have?
Currently unhappy.
Over my adult life, my health and fitness have yo-yoed even though the overall trend has been athleticism and fitness (rowing in college, running after college, yoga, rollerblading, rock climbing, swimming). Since 2010 the yo-yos have all been because of health problems that utterly derailed me for months or years at a time. I would eventually get back into a routine, with running being my go-to activity. I like 10K's best, but have also done half-marathons, a marathon, and a 200-mile relay race.
As others have noted, weight is not a proxy for health. In college I was at my heaviest...~170 on 5'9" female. But I was very fit as I was a rower. Today I weigh around 130 and although outwardly I look healthy, I have cancer, and I underwent (unrelated) back surgery 3 months ago after being bedridden with sciatica.
Today, I'm doing PT for my back, and I'm managing side effects of cancer treatment. On a good day I get 7000+ steps in (having a dog to walk helps!), but I am not at all ready for anything intense. To wit: I've been doing regular body-weight squats for PT, and the other day I tried do a modified squat where you extend a leg to the side when you come up. It tweaked my back, causing back pain for two days. Gah!
My diet is crap. I've never been a particularly healthy eater; I frequently forget to eat, and then when I'm starving (and hangry) I just grab the nearest carby food. I love carbs and sugar. Yes, I know. I'm open to making tweaks in the right direction (reducing bad, increasing good), but I'm never going to be someone who radically changes her diet a la whole30 or keto etc. I know me and I just wouldn't stick to it; I have an easier time fasting.
But I have started taking Vit D3 and calcium, and am newly committed to staying active and (slowly) building to a good exercise regime that I can keep up for the foreseeable future. Reducing work stress is a big part of that equation, and I am taking steps to reduce the load.
