But the duo expanded their brand by adding lots of variations on the original method. The Cardio class is meant to get your heart rate up, and it does so through an unbelievable number of mountain climbers.
This painful move shows up more often than you could possibly imagine—after push-ups, before and after weight segments, and during yoga-like sequences. Mountain climbers. I’m not kidding.
When we weren’t pumping our knees as fast as possible, we did classic Core Fusion moves like tucking, lunging, and twisting our obliques to the beat with light weights. There’s also a section of modified sun salutations with weights involved (and, um, mountain climbers).
One place we didn’t go in this class? To the barre. But if I did this workout regularly, I’d consider heading to Mount Everest to test my skills. —Lisa Elaine Held
