NPC super heavyweight Casey Bunce trains arms

In this episode of Iron Diaries, Dave and Casey train arms in Fit Nation gym out of Norwalk, California! Casey takes us through his "muscle confusion" arm routine. Short breaks between sets, superseding between bis and tris, short, quick reps, then a long, squeeze rep. This was crazy high volume - 36 sets in 40 minutes! If you've never tried this method, you need to! After the workout, Dave gets a little interview with Casey about his competitive history, and future!
