Well my Daddy said "Son a man needs to stay strong"
Been pumping iron since the day I was born oh
Yeah I'm pumping iron, I just do what I like
I got a one-way ticket to the sweet life

Pumping iron you can't stop me
Pumping iron if you can't out-squat me no
Pumping iron you don't impress me
Pumping iron if you can't outflex me whoah
Look in my eyes and tell me who's been pumping iron

Pumping iron you can't stop me
Pumping iron if you can't out-squat me no
Pumping iron you don't impress me
Pumping iron if you can't outflex me whoah
Look in my eyes and tell me who's been pumping iron
Check out my bis and tell me who's been pumping iron
