Twrist (yes, you’ll be mouthing that name for a minute) is a fitness concept aimed just at the ladies. These adjustable dumbbells allow users to start lifting with light weights and gradually increase as they progress. The basic dumbbell weighs between 2 and 4 pounds. More weight plates can be added to the two ends with a simple click-in mechanism that allows you to quickly add or take away weight to easily transition from exercise to exercise. Their tactile, shaped grip ensures proper hand placement and prevents slippage. It also comes with an e-trainer app that lets you know the muscle group you’re training and how to maximize your workout. Additionally, users can design their own custom workouts by adjusting the weight of the dumbbells. Designers: Chen Yan-Ting & Yeh Hsin
