I did this ab workout in a little over 10 minutes, with 30-second breaks between rounds, but if you need more time, like one minute, go for it. The superman variations at the end were a great way to work the posterior chain (back body) to balance out the anterior core work (muscles in the front of your body).
Because planks get to the deepest part of your core — your traverse abdominis, or TVA — I really liked that Alicia had four different kinds, and the plank ankle taps were my favourite exercise because they're basically planks and single-leg V-ups all in one! If you need a quick ab routine that targets your entire core (and then some), this workout does the job.
