TWRIST is an adjustable dumbbells concept that allows beginners to start with lighter weights and increase the weight as they progress.

TWRIST is an adjustable dumbbells design that is targeted at women, so that they can start lifting with lightweights and gradually increase the weight as they progress. The starting dumbbells should weigh between 2 and 4 lbs. and more weight plates can be added to the two ends.
People tend to think that dumbbells are only used to tone and build up arm muscles, but dumbbell exercises go beyond toning the arms – they can also tone the back and your legs. TWRIST comes with an e-trainer app that lets you know the muscle group that the user is training. In addition, users can design their own custom workouts by adjusting the weight of the dumbbells.
