After he'd bulked up for his role in the film Thor, Chris Hemsworth found that he was too big for his costume. So he ate less and did metabolic circuits to burn calories without sacrificing muscle. A few weeks later, he was the right size and still looked big.

You too can focus on muscle definition, not just size, with this Thor-inspired workout from Eric Cressey, C.S.C.S., the author of Show and Go.

Do This:

Perform this circuit, rest 60 seconds, and repeat three more times.
