I created an email course (also available in book form) about this exact thing! [0]

But a few things I've found really useful are:

The Momentum app, which lets you quickly check off habits in the iOS notification centre widget. [1]

Starting small until the behaviour of a habit is ingrained, then increasing the time and effort. Eg. start with a 15 minute run until you're used to running 3x/week, then increase your time gradually until you're running 45 minutes every time, rather than jumping in the deep end. It's easier to keep up a habit that's small and easy, and to increase the activity once you've made it habitual. [2]

Only work on one new habit at a time, because it will take focus and discipline at first. [3]

Once your habit is solid, develop others by stacking them together. [4]
