Train Your Biceps Twice Over The Course Of Your Split
A smaller muscle group like the biceps recovers from a hard workout more quickly than a larger one like legs or back. You can train it more frequently over the course of your split, especially if your training split lasts five or more days.That being said, how you construct that split becomes crucial. In a worst-case scenario, you wouldn't want to train biceps on Mondays, back on Tuesdays, and biceps again on Wednesdays. Your arm flexors wouldn't be given sufficient recovery time to grow. Nor would you want to train biceps the day before or after a back workout. Strategically working in other upper-body workouts, leg days, or rest days between biceps workouts can help pace your pull-day routines.
Just because you're training your biceps twice over the course of your split doesn't mean you simply have to repeat the same workout. Consider the first workout to be a general mass-building biceps routine that includes movement for both the long and short heads, and the second workout to be one that emphasizes the short head with a variety of moves, grips, and rep ranges.
You can even consider alternate techniques to use—negatives instead of forced reps, partials instead of dropsets—to work the biceps in very different ways as well.
Add A Biceps Workouts After Back Training
One easy remedy for the problem of training the biceps is to do your
biceps immediately after your back workout. (Never train biceps before
back; it would adversely affect your strength on many of your back
movements, as well as your ability to hold on to the bar or handle.)
Most back-day movements are multijoint exercises, so the biceps are
already carrying a significant load. It makes sense, then, to just
finish them off because they're already highly fatigued.
Training a smaller muscle group immediately after a larger one is familiar terrain to most bodybuilders, but usually you're not able to generate the same degree of intensity after you've just finished a bunch of heavy pulls.
That's one reason the second biceps workout should be done on an arms-only day. Here, the biceps won't be prefatigued so you'll be able to hit them with more energy—and more weight—a great combination for maximal stimulus.
Start With A Mass-Builder That Focuses On The Short Head
Since curling movements for the biceps are almost exclusively single-joint exercises, the usual advice to start with a multijoint movement just doesn't cut it here. Choose a movement with which you can move the most weight. For most people, that's standing curls. Standing movements allow you to generate a bit of momentum through your lower body and thus are better leadoff hitters, if you will, in your arm workout.As noted above, a slightly wider grip on the bar (or EZ-bar if your prefer) can shift some of the emphasis to the short head. One approach I've used is to do 2 sets with a slightly closer grip and 2 more with a slightly wider grip (or 3 and 1) rather than 4 sets with the same shoulder-width grip. That allows you to better emphasize both the short and long heads on your different sets right at the start of your arm workout.
Further, don't be shy about putting some challenging weight on the bar at the start of your workout, when your energy levels are highest. After a few warm-up sets, use a weight that causes you to fail at 6-8 reps, the lower end of the muscle-building rep spectrum. If you can do more than 8 reps, add more weight.
Emphasize The Short Head In Your Workout
We spoke about prioritizing a lagging body part in the first paragraph of this article, so by all means add another 1-2 movements that focus on the short head. Your best bet is to target it early in your workout when your energy levels are a little higher. Assuming you did some wide-grip barbell curls as your first movement, consider adding other short-head-focused movements next. Good options: preacher curls, lying cable concentration curls, and high cable curls.Hitting the short head with a different relative intensity—that is, instead of choosing a weight that causes failure at 6-8 reps, choose one that causes failure at 8-10 or 10-12—also allows you to target the short head in new ways.
Adding a second movement from a slightly different angle and with a slightly different relative intensity is the best way to work the short head for better overall gains.
