Progression strategies for bodyweight exercises include increasing complexity, repetitions, or hold duration.

“In the case of bodyweight, it's really hard to add load. Maybe you can put a weight vest on or something. But then, maybe you don't have that, or that's an extra thing, or that can only go so far. So what's my progression strategy going to be? Well, in this case, maybe you just increase the complexity by going from two legs, like say a bodyweight squat, to a single leg squat, or you just increase repetitions, or you increase time you're going to hold it.”
