When it comes to arms nothing ever came even CLOSE to supersetting my bis and tris together. The pump is unbelievable and the feeling of exaustion after the workout is amazing. There are so many great variations.. Barbell curls immediately followed by lying ext., close-grip ez-bar preachers, immediately then close-grip ez-bar overhead ext., cable curls, immediately before/after kneeling overhead cable ext. The list goes on forever. Supersetting arms will definitely KICKSTART your arms into growth..
