Hmmm...
Never mind “just” three exercises...
I’m 92.6, and between the ages of 50 and 80, I spent 4 days a week at a World Gym performing intense workouts...
I regret stopping at 78... But declining 1RMs started, so I just continued as a trainer for a few years...
Since then, my chief exercise is driving my wife to various casinos...
God bless
Good on you for that exercise routine,
Before I got a compound fracture of my right wrist that bone specialist MD fixed with a metal plate and three screws in my wrist, making driving too painful, I did a 15-minute mile on the gym treadmill 5 days a week and used other equipment to build arm strength. I’m 88 and slowly , and I hope surely, building up to that again with walks around the ‘hood and lifting weights I bought at AMZ.
Measured in "our" Earth-years?

Regards,
