I hope your routine becomes easier on you @jrchomestead, I recently made the same change as you (though on a smaller scale) and am only just getting used to my new routine and all the back crunching tasks to be done around the place. Pace yourself as you do not want to be causing any serious long term bodily harm!
With being an older new homesteader my body has developed pains in areas I hadn't used in years. Trying to pace myself :)
Ouch. Try and do some stretching warm up before embarking on big tasks!!
