Peep any recent red carpet and you'll notice some A-list accessories. Nope, not talking about diamonds, but about strong, high-def muscles. Leading ladies in the Marvel Universe, like Natalie Portman and Brie Larson, are training biceps, delts, and beyond so impressively they could pretty much scale a skyscraper or flip a truck-no special effects required.

But are flex-worthy arms only possible with celeb trainers, fancy equipment, and long hours? Not at all, with a time-saving solve. Supersets to the rescue.
