I do one basic thing every day. I go nordic walking in sand (no impact, I can't walk on hard surfaces so this is a must) for as long as I can, with stop offs to do basic streching/range of motion every 30-45 minutes.
There is the place where I stop off to refill my water bottle 3-4 times per walk, There are different heights of pilings, so I use them for modified bodyweight exercises every other day. If I just do 15 of each at each stop so I hardly even notice doing it and I get 45-60 reps of each done. I prefer that to actually 'working out'. I still get the basics in though.
I also very much prefer being active outdoors, the fresh air and sun do wonders for my mental health. Of course, having a moderate climate helps. Yep, very thankful for that.
P.S. Great thread idea!
