This workout lives up to its name - designed to push you hard, but leave you stronger. “What Doesn’t Kill You” alternates between high-impact and low-impact cardio to keep your heart rate up while offering micro-recovery moments. The sequence of high knees, march steps, and shoulder taps primes your body for endurance and resilience training while minimizing rest.

Plank-based movements like climbers and shoulder taps bring in the core and upper body activation, increasing your overall muscular stamina. It’s fast-paced, sweaty, and efficient - perfect for days when you need a quick full-body challenge that tests both willpower and fitness. Make it a regular finisher or a full session to build grit and conditioning.
