I've written a lot before about how bodybuilding and powerlifting are complementary. Recently, I had the chance to sit down with Granite and Iron Rebel bodybuilder Luke Carroll to talk about the differences between the two, specifically with regard to arm training:

In case you just want the cliffs, here are the key takeaways from that video:

  1. Exercise Selection. Choosing the right exercises is paramount, regardless of whether you’re a powerlifter or bodybuilder. If you’re hurting yourself when you’re trying to train, you’ll never make progress!
  2. Performance. This is the first major difference between bodybuilding and powerlifting training styles. Bodybuilders should focus on getting the maximum stretch and peak contraction possible on each and every rep. Powerlifters, on the other hand, should be concerned more with the speed of execution and the positioning of the body relative to a competition movement (the squat, bench press, or deadlift).
  3. Programming. This is the most obvious distinction between bodybuilding and powerlifting. Bodybuilders must use higher volume (that is, more total reps) than the powerlifter will, because volume is a key driver of hypertrophy. Bodybuilders will often also stick with higher rep ranges. Of course, powerlifters can also benefit from high reps — when used appropriately.
