Well, yuh....but ones' personal form factor remains the bottom line, esp. when the hands hit the chassis... Unless your posted pic is a file photo from youth gone by, you've got a built-in 'cheat'. *mock grumble* And it's vaguely reassuring that the 300s' pose a challenge to you, Commanding Grips notwithstanding.... ;)
@asvjerry I look like I can lift more but lower back has increasingly become a weak point. I know lift with the legs, keep back straight etc, but all it takes is one absent minded moment and I get a week of back pain & hobbling :(
Also my grip is a relative weakness (hence the gloves). Alas, the "gym bro" thing was fun for a while but I was not made to lift big #s. In my 40s now I've decided to give up the gym for swimming laps.
Take care of your backs, guys!
