A sigma-bond only binds one lobe to another single lobe.

A pi-bond binds two lobes to another two lobes. Two bonds positioned parallel to each other cannot rotate without breaking. If the bond did rotate, not only would it have to overcome the binding energy of that pi-bond, but it would have to overcome the binding energy of forming a pi*-bond.
