Training hard now in my 40s, I notice very little difference from my 20s. It’d probably be more noticeable were I world-class athlete or something.

The main difference I’ve noted is that it’d take me a day or two to fully recover in my 20s, and now it might take an extra day. I can lift the same amounts relative to my progression, I am gaining muscle as quickly, and I’m not injuring myself.

It helps that I am not overtraining now and I was then, by force. Thanks, US Army.

If someone tell you that you can’t get really strong and muscular in your 40s, they probably are just attempting to keep you down at their level of apathy and lethargy. Don’t listen. Just show up looking all strong and fit and then avoid them after because they are an anchor.
