The
term plyometrics is usually used to refer to explosive lower-body exercises
such as skips, hops, jumps and bounds. However, plyometric training is also
important for the upper body as well. According to the principle of
specificity, muscles adapt to how they are trained. Therefore, doing jumps can
improve lower-body power, but it will not have any affect on the muscles of the
upper body. If the goal is to help improve upper-body power for activities like
swinging a racquet, bat or club, or simply to have more strength to handle
common tasks like picking up a child or carrying a heavy bag, then it can be
important to do plyometric training specifically for the upper body.
Plyometric training was originally called
“shock training” by the Soviet sport scientists who developed the technique.
Plyometric training works by initiating a rapid contraction of the muscle
fibers, which places tension on the elastic connective tissue. The faster the
elastic tissue lengthens, the faster and more explosively it can shorten, which
leads to higher levels of muscle power output.
When starting a plyometric training program,
whether for upper- or lower-body muscles, it is important to start with a low
volume of low-intensity exercises because of the magnitude of forces placed on
the muscle and connective tissue. For best results, plyometric training should
focus on only a few repetitions at a time so the maximum amount of force can be
applied with each rep.
Upper-body plyometric exercises can be
performed using body weight only or equipment such as medicine balls, sandbags,
dumbbells, barbells and kettlebells. Medicine balls, in particular, are an
excellent tool for developing upper-body power because they can be both thrown
and caught. When catching a medicine ball, the muscles are rapidly lengthened,
which allows them to explosively shorten during the throwing phase, thus
providing the elastic energy for the plyometric effect. Throwing a medicine
ball allows you to accelerate all of the way through the movement to create the
highest level of force possible as the ball leaves the hands.
It is important to note that there are two
specific types of medicine balls: live and dead. Live medicine balls bounce and
are good for exercises requiring an explosive return. Conversely, dead balls
are filled with gel or sand and do not bounce when hitting the ground. When
learning explosive upper-body exercises, it is recommended to start with dead
balls or sandbags to teach proper throwing form before learning how to catch
and decelerate a ball. It is also important to allow enough time between sets
for the muscles to fully rest and recover to prepare for the next set of
explosive actions.
To develop optimal levels of upper-body power,
it is important to involve the entire body and generate force by keeping the
legs firmly planted on the ground. Pushing through the ground with the lower
body can use the ground-reaction forces to rapidly accelerate the object being
thrown from the hands. The following workout is effective for developing upper-body
power. An additional benefit is that muscular power is generated by the larger
type II muscle fibers responsible for creating shape and definition in a
muscle, which means these exercises can help improve an individual’s physique
as well.
(6-8 reps, 2-4 sets, 45-60 second rest
interval)

Use a dead ball (or sandbag) so it doesn’t
bounce. When throwing the ball down, sink into the hips (like dropping in to a
squat), then scoop the weight up and quickly perform the next rep.
(6-8 reps, 2-4 sets, 45-60 second rest
interval)

Sink into the hips (like preparing to jump),
explode up and push the ball straight up in the air. Allow the ball to fall to
the ground before picking it up for the next rep.
(6-8 reps, 2-4 sets, 45-60 second rest
interval)

Sink back into the hips and hold the ball in
the hands with the arms straight. Explosively drive the feet into the floor and
press the hips forward while extending the body. Complete the move by releasing
the ball behind the head.
(6-8 reps, 2-4 sets, 45-60 second rest
interval)

This exercise requires a rebounding wall or a
partner. Stand with the feet approximately shoulder-width apart (if throwing
from the right side, the left foot should be forward). Hold the ball in both
hands and rotate over the right hip (allowing the left foot to turn in). Next,
push the right foot into the ground to start the rotation. As the shoulders
face forward release the ball from in front of the hip, angling it so that it
either goes to the partner’s right hip (when facing each other) or, if using a
wall, so that the ball bounces back to the right hip.
(6-8 reps, 2-4 sets, 45-60 second rest
interval)

This exercise requires a rebounding wall or a
partner. Stand with the feet hip width-apart and hold a ball in both hands at
chest level. Sink into the hips and drive the feet into the floor while
exploding the ball forward away from the body. If working with a partner, allow
enough space for the ball to travel between partners. If using a wall, don’t
stand too close to it.
