Join Diane for a kickboxing-style cardio session built around four blocks of interval work, each pairing two exercises before combining them into longer combo intervals. You'll cycle through jabs, cross punches, roundhouse knees, crescent kicks, sidekicks, sumo squats, and traveling lunges, working from both orthodox and southpaw stances as the session progresses. The format layers in increasing complexity and intensity with each block, pushing you to sustain energy through 90-second combo intervals while shifting between upper and lower body emphasis to build cardiovascular endurance. This is a single-workout day.
