My personal opinion from research and working out the past few months. You do not have to do three sets. Because technically each exercise is one set when it comes to abs.

If you are pushing yourself, then no matter what you do, you’re doing it right.

With every study that’s published, scientists become more convinced that having a healthy gut leads to having a healthy body.
