Working on the biceps and the back at the same time is possible. Rowing and pull-ups are two excellent exercises to work these particular muscles. Like all compound-movements, they are more effective than just targeting one area.
Supine pull-ups are very good for the biceps. But the mistake that we tend to make when we work on our body weight is that we don’t work with weights.
Fitness coach Jeff Cavaliere suggests an exercise that is more effective. First of all, do weighted supine pull-ups until you can’t do anymore and once you are at this point, take off the weights and try to continue and do more reps than you did with the weights.
This exercise builds up your biceps and your back muscles. You best believe that you’ll feel it!
