V 'hello I am in my 40s' toot, but a few months back I started sitting on the floor a lot more and getting up without using my hands and I'm really noticing better flexibility and strength, would recommend
I'm strong in a very specific limited way, but also I'm about 90kg and my body is mostly a dopey hulk which crashes about the place, so working on my functional strength seemed to be a good idea...
(also being able to get up after a fall is an important not-dying skill)
