Join celebrity trainer and wellness coach Jenna Willis as she takes you through an amazing 15-minute HIIT workout with her real-life BFF, actress and producer Liza Koshy! These two will keep you on your toes (sometimes literally) as they demonstrate variations on squat pulses, curtsy lunges, push-ups and Koshy's favorite Pilates abs. This workout is only 15 minutes, but you're going to get an amazing HIIT workout with a bonus ab section to really burn out that core!
