I'm having a lot of trouble motivating myself to exercise. I want
to exercise, and I know all the good and rational reasons to do so, but that doesn't get me off the sofa. I'd like to devise a plan and I know I'm more likely to stick with it when I have specific goals.
However, 99.9% of exercise plan advice out there is geared towards losing weight, and I don't want to do that (BMI is 19.7). Likewise, I'm not really looking to compete in running races (I completed a marathon a few years ago and it was great, but it hurt my knees and I haven't really run since). But, I also know I'm not 'healthy' healthy - I have recurring lower back problems and I've tested a little high on HDL cholesterol (suspect too much dairy). I realize I go in cycles of exercising (the marathon, before a 10-day hike when I knew I didn't want to get left at the back, college crew team) but I'd like to make it more sustained and holistic.
I (finally) found this previous question
but what I'd like advice on is any metrics
I could keep logs on as 'healthy goals'? Resting heart rate? Number of push ups in a minute? What should
I be able to do as a 28/f?
I really welcome any personal anecdotes on this kind of 'general' exercise plan, along with any websites/books/other media recommendations.
