Dethrone’s Cardio Assault class consists of a punishing half hour of one-minute exercises—nonstop. The first minute is on the Air Assault Bike, followed by 60 seconds of intense weight or bodyweight exercises, including TRX rows, Russian twists and box jumps. Then it’s back on the bike, back to the exercise … you get the idea. The workout ends with 10 minutes of abs and core. And if you hit five miles on the bike, you get a free T-shirt! 8868 S.
