Join celebrity trainer and wellness coach Jenna Willis [1] as she leads you through this 10-minute no-equipment upper-body and core workout joined by Paris Nicole [2] and Jai Jordan [3]! You'll get started right away breaking a sweat, thanks to a series of plank shoulder-tap reaches, reverse crunches, toe touches, and more. Though the focus is on your upper body and core, your legs, glutes, and back will still get a little action, too. Ready? All you need is a mat to get started!

Don't miss new episodes of Class Fitsugar, now every Sunday on the POPSUGAR Fitness YouTube channel [4].
