It's not ok to plateau at that level. You will get old, your strength and bone density will go down and it is a lot harder (but still possible) to improve those when you are old. Much better to start with a lot more than the minimum so you have a decent safety margin (and lifelong habits that will keep you healthy for as long as possible).
