Part 3/7:
To effectively work the short head—the larger part of the bicep—Grant demonstrates a straightforward technique. He suggests letting the arms hang freely at the sides while performing the curl. The unique arm positioning, with a slight angle outward, primarily engages the short head of the bicep, providing the strength and bulk that many seek.
Grant notes that this position not only builds the short head but can also minimally involve the long head as well. For individuals aiming for maximum engagement of the short bicep muscle, this method is a foundational move that facilitates notable growth and strength.
