Total body strength without weights?

Ok, so i have never used weights in my life, except for the rare event i pick up a dumbbell, but still. i have never done weight training, and i had a bet with my friend that i could get more ripped than him without weights while he used them. he is a bit bigger now, but i have gotten bigger as well, and i look way more ripped than him. however, everyone tells me what im doing isnt normal or healthy. I have decent strength and muscular endurance, and i can run for miles, but i dont know if theyre right. Is it fine to go only bodyweight workouts? personally i dont like weights, because bodyweight gives me functional strength, but still. what do you all think?
