The biceps recover faster than most other muscle groups in your body. For example, your chest, back, and quads are muscle groups which require a considerably greater amount of recovery than the biceps.
Because the biceps are so small, many find it possible to do two biceps workouts a week, using minimal number of overall sets (6-8) staying within the bodybuilding rep range (6-12).
Try to adopt good form while performing these motions. It can be easy to get injured if you choose to cheat or perform sloppy reps. Although applying the cheating method can prove to be beneficial in certain circumstances - just don't do it accidentally or for every set!
