I’ve got 20 inch lean arms - I know far more about muscle building and retention than you. I train just as hard to maintain them as I did to get them there.
The people who say “oh it’s easy to maintain” LOL it’s easy to maintain 16 inch arms.
I am a competitive bodybuilder…
> I train just as hard to maintain them as I did to get them there.
Are you enhanced? Were you enhanced when you built the 20” arms? If so, yes I agree.
Edit: With 20" arms, there's nearly 0% chance you're natural. You can't compare your enhanced experience to naturals.
I noticed it myself with cycling. Took 8 years off the bike, when I started up again I was nearly back to my old FTP in about 2 months despite starting from basically zero. Muscle memory is real, where I am now as a returning cyclist would take a pure beginner cyclist at least 4+ months to get to, fitness wise.
That said, you do have to work somewhat hard to maintain. With cycling, just 2 weeks off the bike is enough to see a VO2 max drop of anywhere from 4 to 7%. After just 4 weeks, your glycogen storage capacity decreases and you start rapidly losing fitness. After 2 months, you are basically now out of shape.
Detraining happens faster than most people think. And therein lies the danger with over reliance on LLMs for your cognitive skills. Detraining there happens just as fast, skills atrophy in a matter of weeks, not months or years.
