Get those guns in shape for hunting season (I'm allowed to say that in a dude post, right?) with this variation on the biceps curl. Place one leg on a box or weight bench. Prop the elbow of the same side on the inside of your knee. Raise and lower the dumbbell. Dude tip: You must point to your bicep with your free hand, just like Megan is doing here. Kissing your bicep is optional but encouraged.
