Interesting - thanks for sharing the links! I'll give them a try. My "new" thing has been Pilates. I saw videos of an instructor on TikTok - and after ogling appreciating her fitness, I thought it might be a good counterpoint to my weightlifting routine inasmuch as it's focus is on bodyweight and hand weights. It's part of an online program called Ladder, and the benefit of that is that should I desire, I can switch to a whole other universe of fitness activities should I find Pilates not to be my thing. I thought I'd only do 3-4 programs a week - but now I've upped it to 6 days a week.
Still, after a few weeks, I'm finding it does precisely what I was looking for - exercising muscles I wasn't working on, enhanced flexibility, and a great warm-up for my heavy lifting.
On the cycling front, I'm thinking of getting rid of my bicycles - and now is the time of the year to do that. I'm thinking of that for 2 reasons - one is a fall at my age - no longer desirable and secondly, I really don't want my wife to ride - as it is even more undesirable for her to have an injury - where risk of crippling is much higher due to her bone density issues. If I abandon cycling, it is very unlikely that she'd go out on her own.
