Look up the name Frank Beeler. Here is a pic of me and him.
He was 50 there, and he used to say "I can't believe how I keep getting stronger as I get older"
You will find that he holds International Bench Press records across the world in drug tested events.
So, in essence, his answer would have been "no, there are no limitations"
That weight he was pushing there was not a 1RM, he was repping with it. He only wanted me to stand there quietly "just in case"
He didn't scream and holler or arch his back as he pushed the weight up. He didnt work legs or arms or anything. He was just a bench presser.
He was a client of mine for years, if you ever saw him do anything it was bar benching, 1RMs, Iso-holds, or competition lifts. Once in awhile you might see him on a recumbent bike B.S.ing with someone for 20 minutes or so.
