Joint health, bone density, and strength/muscle mass are things you will miss out on if, say, you just play ultimate frisbee. But getting stronger doesnt have to be 3 sets of 8 on bench. You can get essentially the same health benefits by engaging in sports that train strength, like martial arts, acrobatics, or rock climbing. That said, many people who do any kind of physical activity aggressively typically find that they enjoy lifting at some point in their athletic careers, as lifting itself can improve athletic performance and ward off sports injuries, due to the controlled and progressive nature of gym work, as compared to the more chaotic nature of real-world activities.
