Justin Timberlake and Jessica Biel certainly make ab work look easy, but we know how challenging a plank series can be. Ahead of the new year on Wednesday, the duo shared quite the impressive core workout on Instagram, and yep, my abs are sore from just watching. In the video, the two demonstrated a series of plank reaches, hip dips, shoulder taps, and side plank exercises, all while holding solid planks.
As they moved through each rep, the pair was perfectly in sync with not only each other, but also the inspiring — yet admittedly intimidating — training music. Watch the two power through their workout with ease ahead.
