Yep, I'm with you on the gym, NG. I would go if I could, but I really can't. My bursitis and knee surgery make me a non-candidate for most of their exercise machines.
Instead, I do a moderate low-impact walk around the neighborhood every day and just grimace now and then. After about 3 miles (and small change), I feel I have done my due diligence to get off of my BFA for a while. Though earlier in the week I was cleaning yard debris after a storm. Anything that was loose on our trees hit the lawn during three days of high winds. But, after 16 x 39-gallon leaf bags and 3 large garbage cans worth of tree droppings, the place almost looks presentable again. My back hates me, but that is an on-again-off-again thing anyway.
