Larry Niven wrote some short stories about human colonists on a 3.0G planet (
Jinx, orbiting
Sirius A, is a massive moon of a gas giant). Short lifespan due to heart failure, very strong otherwise:

"Jinx, orbiting Sirius A, is a massive moon of a gas giant (simply called
Primary), stretched by
tidal forces into an egg shape, with surface gravity at the habitable areas near the limits of human extended tolerance. The poles lie in vacuum, the equatorial regions are
Venus-like (and inhabited only by the Bandersnatchi); the zones between have atmosphere breathable by humans. Jinx's poles become a major
in vacuo manufacturing area. Jinxian humans are short and squat, the strongest bipeds in Known Space. But they tend to die early, from heart and circulatory problems. There is a tourist industry which provides substantial useful interplanetary trade credits for the Bandersnatchi, who allow themselves to be hunted by humans under strict protocols."
