This could have been a story by John Campbell. The description not quite fits that of Aarn Munro, a native of the Jupiter colony. Adapted to a gravitational pull more than twice Earth, Aarn has much denser bones and more powerful muscles (as well as being a superman in almost every other regard), and is able to lift both his sidekicks Spencer and Carlisle with one arm:
Jupiter, a world with two and a half times the gravity of Earth,
required strength in its people, and speed, too.
On Earth, Aarn weighed nearly three hundred and fifty pounds. For the
first twenty years of his life he had lived on the giant of the system
and had developed such strength as no Terrestrian ever dreamed of.
More than once he had proved his ability to lift and walk off with a
ton and a half of lead.
