I try, you succeed - A way to tell someone they’re just a weakling and the other

A way to tell someone they’re just a weakling and the other is a total beast who doesn’t even break a sweat.

I tried to lift the weights. You lifted them like they were feathers. I’m just a weakling.

I tried to win the argument. You won it while I was still talking. I'm just a punchline.

I tried to finish the race. You finished it and started a new one. I’m just a slowpoke.
