TWISTLOCK™ Dumbbell Overview
Before using, please take a few minutes to familiarize yourself with some initial steps and a basic understanding of the operation
of your new TwistLock™ Dumbbells.
Adjusting Weight
For added safety, the TwistLock™ weight adjust system can only be used when the dumbbell is docked with the cradle that
holds the dumbbell.
Adjustment Window Weight Range (in pounds):
With the dumbbell weight plates aligned properly in the cradle and the dumbbell handle fully engaged into the cradle, you must
ensure that proper rotation of the handle and weight selection occurs before using your dumbbells. Turn the handle to each
weight selection (clockwise and counter-clockwise) and ensure that each of the plates are securely engaged by pulling the han-
dle (with weights attached) out of the cradle. Once you have confirmed that the handle and weight selection works properly, you
are ready to begin using your dumbbells.
No knobs to turn, pins to align, or levers to slide – just twist and go! The patented TwistLock™ technology allows quick and
easy weight adjustments with the simple twist of each dumbbell handle. You never have to take your hands off the dumbbell
handles – simply place them into the dumbbell cradles and twist the handles to adjust the weight. Once the desired weight is
shown in the adjustment window, you are ready to go!
Handles
The TwistLock™ dumbbell handles are designed to provide you with a secure and comfortable grip during your workouts. The
handles (without any weights attached) weigh just 5 lbs each. This allows beginners to perform exercises with lighter weights.
For convenience and ease of use, the handles are designed to work in either orientation, so you don’t have to worry about plac-
ing it back into the cradle in the wrong direction.
Cradles
Each of the TwistLock™ dumbbells are designed to work with either of the included cradles. They perform two functions:
1. They keep the weight plates in the correct position in order for you to properly engage and disengage the dumbbell handle
to the cradle with weights during workouts.
2. You can only make weight selection changes when the handle is fully engaged into the cradle. This is part of the
TwistLock™ dumbbell design that allows you to make weight changes safely, quickly and easily.
Weight Plates
The TwistLock™ weight plates are designed to work together. The shape of each plate features grooves that allow weight
plates to join together in an up/down orientation. When you adjust the weight by twisting the handle (which can only be done
while in the cradle), a selection rod extends or contracts into the appropriate number of weight plates. This selection rod keeps
plates from moving in the up/down orientation and keeps the selected plates securely attached to the handle during workouts.
Each of the large round weight plates weighs 5 lbs each, while the half sized plates (2 per dumbbell located closest to each end
of the handle) weigh just 2.5 lbs each. The 2.5 lbs plates are picked up on every other weight selection in the weights ending in
“0” including 10, 20, 30, 40, and 50 lbs.
