This five-exercise ab circuit can be tacked on to a regular workout or used on its own, two or three times a week. The best part? The entire circuit can be completed in 16 minutes or less.
Perform the exercises back-to-back with no rest. When you've completed all of them, that is one round. A "double count" means to complete twice as many reps, so you're doing the same number of reps on each side. Remember to engage your core to get the most out of these moves!
Complete four rounds total.
Beginner Tip: Take up to two minutes of rest between rounds.
Advanced Tip: Take up to one minute of rest between rounds.
