The old out of sight out of mind trick works really well here! Putting a savings account or two at a different bank than the one which houses your main checking account will reduce the temptation to keeping pulling savings into checking because you won’t see it. It can start to accumulate a nice nest egg (assuming you regularly contribute to it). You also can’t move the cash quickly as it generally takes about two business days for those funds to clear, so it’s harder to take a little out in a moment of weakness. That being said, you probably want to still have some savings at your main bank incase an emergency pops up and you need to move cash quickly.
