The
Problem: Your kicks make contact but they have
no IMPACT behind them.
To
develop a powerful kick that'll do major damage,
you need to train the core to deliver and deal with
the massive rotational and impact forces involved.
Otherwise, you're just flailing your leg around
and annoying the other guy until he puts you on
the ground.
The Solution: Double Dumbbell
Swings
This
may sound a bit strange, but with this exercise
you're essentially going to be doing a cross-country
skiing pole motion with your arms while holding
dumbells in your hands. Sounds easy, right? On paper,
sure. In reality, you're going to be in for a shock...
First
think about where the tension from the opposing
momentum of the dumbells moving in opposite directions
is going through: the core.
As
one dumbell is swinging down, the other is swinging
up and it falls to the deep muscles of the core
to stabilize the spine and body and to also provide
muscular force to help keep those dumbells swinging.
This
opposing torque on the abs results in TREMENDOUS
elastic/plyometric workload on the deep muscles
of the core, especially when both dumbells are at
the bottom of their swings and heading back up.
All the momentum of those dumbells swinging is now
going to go directly through your core.
How To Do It:
First,
pick up two dumbells, one in each hand, and stand
up straight. Start fairly light (use approximately
what you can do for 10 to 12 reps on the dumbell
curl) - you will be working your way up to heavier
weights as you get stronger and more experienced
with the exercise.
Keep
your feet close together (a few inches apart at
the most). If your feet are set too wide, the dumbells
will contact your thighs at the bottom of the movement.
Keeping the feet closer together also forces the
abs to do more of the stabilizing as your body can't
rely on the legs to absorb as much of the momentum
of the swinging dumbells.
In
order to get a good swing going, this exercise will
require a carefully timed dip in the knees.
So
on your very first rep, start by dipping slightly
in the knees then popping back up. As you pop back
up, use this momentum to start your right dumbell
swinging forward and up and your left dumbell swinging
back and up.
As
the dumbells start to come back down, dip your knees
down again. As your left hand swings forward and
your right hand swings back, pop back up strongly
again.
You
are using your legs to add momentum to the dumbell
swings, getting them up higher and giving you the
ability to use heavier dumbells.
Repeat
this dip and pop up EVERY time the dumbells come
down to the bottom and start to come back up.
As
you do this exercise, try not to let your torso
twist back and forth much. Do your best to keep
your shoulders and hips square and unmoving so that
all the torque goes through the core and so that
you don't get any sharp twisting movements in the
spine. Your shoulders WILL move somewhat (there
is no getting around it) but by trying to keep still,
you will minimize the movement.
Keep
your arms rigid and locked into position as you
swing the dumbells up and down. For height, you
want to aim for about shoulder height in front of
you and a little lower with the dumbbell behind
you. Keep control of the weight and your torso throughout
the movement - no wild swinging. Exhale forcefully
each time you pop up (imagine as though you're trying
to blow the dumbell forward).
If
the dumbells are too light and you find the exercise
is not challenging your abs after a few reps, increase
the weight.
Keep
going for as long as you can with good form. When
you can't swing the dumbells very high or you feel
your core strength starting to give out (i.e. your
shoulders and hips start twisting too much for your
core to control), stop the swinging and set the
dumbells down.
At
this point, you're going to be huffing and puffing
like crazy - this exercise works not only your entire
upper body, but also involves your lower body strongly
each time you use your legs to pop up.
So
how heavy should you go with this exercise? That
will depend on how strong your core is and how heavy
your dumbells go! You can build up to some very
good weights with this exercise - I've personally
gone up to a pair of 85 lb dumbells.
The
more weight you can safely use with this exercise,
the stronger and more powerful your entire core
area is going to get and the harder you're going
to be able to deliver your kicks.
The Bottom Line:
The
Double Dumbell Swing is one of the powerful core-power
exercises you can do. It's extremely practical and
VERY functional, especially for improving kicking
power and core explosiveness.
