I have a home gym, so I'll often lift in my bathrobe/dressing gown, lol.
The only real item of gym clothing I wear are Asics MatFlex 4s. They feel pretty close to barefoot, but with good stability/grip.
Have you seen any noticeable benefits from the D3? I've taken it for a couple of years, just sort of assuming I'm deficient in vitamin D (since a lot of people apparently are, and I don't get a huge amount of sun).
Hope everyone's well. I've been drifting away from Reddit a bit, recently. Good to find another forum (with a ton of boards) for interesting/open discussion.
