You know what January means? Time to start on those New Year fitness resolutions. Like, immediately. Chop, chop!
If one of your goals happens to be tummy-focused then stick around because we've rounded up five hardcore ab workouts that are sure to whittle your middle in no time. Or, more accurately, in just a few weeks.
That's right, we're borrowing a few workout tricks from Jessica Alba, Brooke Burke and more celebs with fab abs. So allow Instagram to become your personal trainer by watching these videos below.
How does Kendall Jenner keep her stomach trim? The Keeping Up With The Kardashians star's trainer Gunnar Peterson puts her to work with some challenging exercises.
Peterson instructs the 19-year-old to keep her feet up and core engaged while throwing a ball overhead at the trampoline. If you don't have a trampoline, try substituting a friend. The model makes it look easy, but we're pretty sure it'll only take a few reps to feel the burn.
Jessica Alba has always been known for having one of the best bodies in Hollywood, and the mother of two works hard for that title. Her Instagram video teaches us how to combat that lower belly bulge.
Alba admitted she was sore after putting herself through a series of ab-shredding double-leg lifts.
Another difficult drill is Padma Lakshmi's extremely intense plank routine. If you're not in the same shape as the Top Chef host, try doing this without the pushups and weights.
