I don't actually formally excercise, as in go to a gym, or take time out of my day to walk or jog or lift weights. I just don't have time. The reason I don't have time is because I'm too busy push mowing, weeding, hoeing, pruning, trimming, building, cleaning, scrubbing, canning, cooking, etc.
I traded in my old hobbies of surfing the net, reading, sewing and movie watching to more physical home and farm productive activities. Once school starts, my job is also very physical and keeps me on my feet moving for most of the morning and afternoon. (ugh, I dread going back! haha!)
I guess what I'm trying to say is that I have reduced my waking hours moving/sitting ratio from a previous 5%/95% to 95%/5%. It has been working well for me so far!
