Offset weight selection
As indicated above, proper selection for a given weight is
accomplished by selecting that weight number on both
ends of the dumbbell. For example: to select 20 lbs, one
must dial both adjustment knobs on the dumbbell to the
number 20. By selecting the same number on both sides
of the dumbbell, you will replicate a common dumbbell,
this is to say, a balanced dumbbell with equal weight on
both sides. While this is the most common form of weight
selection and will be used in the vast majority of work-
outs, the Bowflex

Dumbbell offers a useful
and unique workout alternative known as offset weight
selection. Offset weight selection involves using a differ-
ent weight setting on one side of the dumbbell relative
to the other. Doing so can be a powerful muscle develop-
ment tool during certain workouts, such as the biceps
curl. The SelectTech

Dumbbell functions exactly the
same way whether you have selected balanced or offset
weights. The only exception is that when you are using
weights. The only exception is that when you are using
offset weights, you must return the dumbbell to the base
in the same orientation that you removed it. When you
have offset weight selection the combination of weight
plates selected will not be the same on both sides of the
dumbbell. You must therefore make certain to return the
dumbbell to the base in the same orientation in which it
was removed, in order for the weight plates to settle back
into the corresponding vacant slots in the dumbbell base.

Example of offset weight selection workout
Performed traditionally, dumbbell curls strengthen the
biceps, but do little for the forearm muscles that assist in
supination and pronation of the wrist. Supination and
pronation are terms describing a rotating motion of the
wrist. For example, turning a doorknob and turning your
key in your car’s ignition are examples of supination and
pronation. Turning a doorknob clockwise would be the
supination direction, while counter-clockwise would be
the pronation direction. Whether you are training for a
specific sport, or just training to become stronger and
improve activities of daily living, training your forearm
muscles that are involved in supination and pronation
can be beneficial.

These dumbbells allow you to train differently than
traditional dumbbells. By using different weight settings
on either side of the dumbbells, you can use those supi-
nation/pronation muscles during your curls. Using more
weight on the thumb side of the dumbbell will improve
pronation strength, while more weight on the little finger
side will improve supination strength. Not only will you
be strengthening your biceps, but also you can become
stronger in activities involving rotation of the wrist!

The dumbbell weight has been set to 20 lbs on one side
and 30 lbs on the other. The total weight of the dumbbell
is therefore 25 lbs. This 25-lb dumbbell has the weight
distributed such that there are 10 lbs on one side and 15
