What is the ideal and healthy weight for a 510 male at age 33?

There's a range: It depends on age and body build, too. Muscular people are fine to weigh more. Most adults are slimmer in their 20's, and heavier in their 40's onward. A ballpark number for men can be 106 pounds for the first 5 feet of height, plus 6 pounds for each additional inch above 5 feet. In this case, 106 + 60 = 166 pounds. A man in his 30's can be 155-170 pounds or thereabouts.
