Abacus
Abacus is an F45 favorite that is cardio-focused with fewer stations and a twist: increasing work time, then decreasing work time over the workout duration. Climbing and descending repetitions in this fitness pyramid is a fun, intense test of your cardio capacity. Don’t underestimate the simplicity of this 6-station session; Abacus will leave you drenched and gasping, asking where all those inches on your waistline disappeared to.
