Looking for a challenge? This full-body HIIT session is perfect for you. Join celebrity trainer and wellness coach Jenna Willis [1] as she leads you through a 30-minute high-intensity cardio and strength workout alongside class members Paris Nicole [2] and Taylor Ashlynn [3]. Willis keeps the intensity high with a series of jumping jacks, planks, lunges, and more, but you can level it up even more by grabbing an optional pair of dumbbells.

Kick-start your workout routine with POPSUGAR's new line [4] of affordable fitness equipment available at Walmart.
