This provides you with a unique opportunity to perform the full range of motion, with increased recruitment of muscle
biceps muscle fibers at the top portion of the curl.
For biceps, it's a bit tricky as there are not many exercises that are practical to switch between AND which are different enough to stress
the bicep muscle fibers differently than just two types of curls.

It's important to know that the
biceps is mainly composed of fast - twitch
muscle fibers, which are able to produce quick and powerful contractions.
This isn't a call to abolish all tried - and - true techniques and switch to «shocking» your
muscles with something completely new every week — which is a terrible idea by the way — it's a reminder that in order to resume growing your
biceps, you need to hit their
muscle fibers, which are predominantly of the fast - twitch type, with more intensity.
The supinated grip, which is more isolating and restrictive than its counterpart, will allow you to better target your
biceps as secondary
muscles, while the pronated grip engages more
muscle fibers and creates a better midrange stimulus on the back
muscles, primarily targeting the lats and anterior delts.
Since these three exercises have complementary strength curves, by grouping them (or any other three exercises which offer high tension at different parts of the range of motion) in a
bicep tri-set, you will enable maximum tension throughout the entire range of motion, activate all available
muscle fibers and get a truly incredible pump.
The most important reason for this phenomenon is the fact that the brachialis
muscle has more slow - twitch
fibers than the
biceps, and therefore, has more of a stabilizing role compared to the
biceps brachii which is meant for faster, more explosive work.
To help optimally stretch the
muscle fibers of your
biceps, make sure to stretch out your arms as far as possible on the release.
If you make your
biceps use more and more
muscle fibers when you hold them for more than the necessary amount by a second or two when you get to the top of the movement, you'll have even better results.
A classic way to place more resistance on the
biceps brachii and destroy those stubborn
muscle fibers.
There is nothing wrong with performing multiple sets of moderate weight
biceps curls for example but to maximize your arm development you should be thinking about working all three types of
muscle fibers within your arms.
If your primary objective is increasing your back's width, go for wide - grip lat pull - downs, as they better stimulate the teres major and upper - lat
fibers, in addition to working the
biceps, forearms, triceps, rotator cuff
muscles and posterior deltoids.
For example, when you pick up a glass of water from the table you recruit just a few
fibers in your
bicep (among other
muscles) in order to perform the movement.
EMG studies of the long head of the
biceps brachii show that
muscle fibers in the lateral portion of the
muscle are recruited for elbow flexion,
fibers in the medial aspect are recruited for supination, and centrally located
fibers are recruited for non-linear combinations of flexion and supination.
Because the
biceps and triceps have a less overall volume of
muscle fibers it doesn't require as much stimulus to fatigue these
muscle groups and deplete glycogen stores.
This training technique is brutal and incredibly effective for targeting all three major
muscle fiber types in the
biceps and triceps.
It's a simple motion: some
muscle fibers (such as your
biceps) contract to move the limb and then opposing
muscles (such as your triceps) contract to move it back where it was.
They report the proportion of type I
muscle fiber in the long and short head of the
biceps was 39 % and 37 %, respectively.
They reported that the proportion of type I
muscle fiber in the
biceps was 39 %.
Therefore, the limited information currently appears to suggest that the
biceps displays a predominance of type II
muscle fibers.
This important new study used the latest methods to determine the
muscle fiber type of the
biceps femoris (long head), which is the hamstring
muscle that is most often injured during sprinting.
