Offset weight selections.
The chart to the right is a quick reference to determine the amount of weight offset to
one side of the dumbbell.
The amount of weight listed in the Difference column indicates the difference
between the two weights selected with the dumbbell adjustment knob.
The symbol “+” indicates the amount of offset weight on the heavier side of the
dumbbell.
Although you can continue to increase the amount of weight offset, it is not generally
necessary to offset the weight more than 20 lbs (9 kg).
Start the biceps curl with a neutral wrist and forearm position (palm facing leg). As the curl progresses
from the start to finish position, the wrist should be rotated progressively outward (palm up). During this
curl the user will be lifting the weight of the dumbbell (25 lbs [11.4 kg]) with the biceps but also lifting
the offset weight of 5 lbs (2.27 kg) with wrist rotation (supination). Unlike a conventional dumbbell that
is balanced end to end, this offset weight will require more muscle activation and therefore develop the
forearm and wrist.
The following chart provides the total dumbbell weight for various combinations of weight settings.
