Every once in a while, you deserve a workout that’s just about feeling jacked, pumped, and dangerously aesthetic.
ARMageddon builds capped delts, full biceps, and crisp triceps without trashing your joints.
Stability → isolation → pump.
It’s the perfect “mirror muscle” day for anyone who wants to walk out of the gym looking like they’re on the cover of a superhero comic.
This workout does not include a cool-down stretch, but we have some great options here!
