@janeevans89 I still push myself, but I am more mindful of my age and injury risks. I can comfortably bench 220-230 but would like to reach 250 before the end of the year without destroying my shoulders, lol. I definitely don't lift as heavy as I did in my 30s and 40s when I was training for competitions, but I was also eating a lot more back then and using high doses of PEDs. My diet is more protein than other macros, but my total caloric intake is designed for slower growth and a leaner physique. I tore the long tendon of my bicep last year doing 60lb dumbbell curls, so I try to keep my ego out of my lifts so I'm not tearing myself up. Gains in strength and muscle volume are more gradual but still happening, so that keeps me driven.
To the question of gear (cuz someone will most likely ask), yes I do, but doses are considerably lower and tailored to keep my testosterone in upper normal ranges. My background is in medicine, so I frequently have my blood checked for hormone levels, hematocrit, hemoglobin, liver, and kidney function (etc.) and an EKG done 2x a year to make sure blood work and vitals remain within normal ranges.
Yes, diet is essential - especially as we age - to minimize sarcopenia (age-related muscle wasting), keep body fat levels low, and provide the energy and calories needed to support fitness goals. Gains and loses are made in the kitchen as they often say, and I put a lot of time into meal planning every week - but I've done that for so many years now that it's less a burden and more straightforward due to habits I set up long ago.
My son's lack of strength is largely due to his poor eating. He doesn't eat a lot of crap but he also doesn't eat enough to support his strength goals. Unfortunately, at 22, it's harder to change his mind. He's learning on his own, though, and is making a better effort to improve his nutrition. It's his lack of consistency that really slows his progress, but he will figure it all out when he really wants to, lol.
Good luck on your journey. Keep grinding and smashing those weights as long as you can!
