This +100. This is what my bass tutor always advises. Start off slowly, get your muscle memory locked into it then increase the BPM. He recommends 2 BPM at a time but you could try 5 BPM. Only up the tempo once you've mastered the previous one.

This works for me as well, I will keep increasing the tempo until I can play it slightly faster than needed - which makes it seem easier at the required tempo.
