Gymnastics requires a lot more training and skill than lifting up and putting down iron. There are far less body weight exercises that you can do without specialized equipment than with dumbbells or barbells, because with bodyweight exercises you always have to push, never pull (with exception of pullups). Bodyweight exercises also generally take much longer to reach fatigue than weightlifting.

That's why I think weightlifting is better for the average person for health, although whatever gets one to actually exercise is what one should be doing!
