Rolling Extensions on Ground
Category: Accessory
Muscles Targeted: Triceps
This is an old favorite. The rolling extension is somewhat of a cross between an extension and a press; for lack of a good description, it's a sloppy extension with a little bit of press thrown in.
To do this, lie on the floor and hold the dumbbells at arms length. Bring the DB's to the side of your head, resting them on the floor. From here, let your elbows dip slightly and extend the arm.
