Why do we not have awkward lumps everywhere or just bulges off this side or something?

Most of your body is already pretty symmetrical.
Basic symmetry helps you move. For example, it’s easier to lift a barbell with forty pounds on each side than one with ten on one side and seventy on the other.
Your body naturally wants to distribute your weight evenly, usually around your hips/belly because that’s where it’s easier to carry.
Your body knows to do this because it’s coded in your DNA and it got there over millions of years of natural selection as your more symmetrical ancestors lived longer and procreated more than their less symmetrical siblings.
