ARMageddon Workout
Jason builds capped delts, full biceps, and crisp triceps without trashing your joints. Stability moves into isolation, then straight into the pump for the ultimate mirror muscle day.
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!
