Separate exercises for biceps and triceps? Not really necessary...
Short of time, but still want to do your resistance training? You can save time by leaving out the exercises for your biceps and triceps. Sports scientists at the Universidade de Brasilia discovered that biceps and triceps develop just fine when you do multi-joint exercises such as bench presses and pull downs. If you do these, then single-joint exercises for the biceps and triceps don't add anything extra.
Study
One group did so by doing bench presses, lat pull-downs, dumbbell inclined presses and dumbbell rows [MJ]. The other group used the same exercises, and did the same amount of sets, but added two single-joint exercises to their routine: biceps curls and triceps extensions [MJ+SJ].
The researchers measured the muscle mass and muscle strength in the subjects' upper arms before they started the training schedule and after the students had been doing the resistance training for 10 weeks.
Results
Same story for the amount of strength that the subjects developed when doing biceps curls. The subjects who had done single and multi-joint exercises built up a tiny bit more strength, but the differences were not statistically significant. So both groups built up the same amount of strength.
[Hmm... Would the differences between groups still not be significant after six months of training?]
Conclusion
"Thus, coaches and athletes could save time by not including single-joint exercises in the training program and still achieve gains in muscle size and strength."
"Future studies should analyze the use of single-joint exercises over longer periods of time and in different populations. It would be also interesting to study this concept in lower body muscle groups."
