Julu smart instantly adjustable dumbbells are powered by a digital platform. This allows users to easily change the weight via an LCD panel or smartphone app. The dumbbells range in weight from 2.7 kg to 16.3 kg, making them suitable for both light workouts and gradual strength building. Each dumbbell is equipped with a unique locking mechanism that prevents loosening during lifting. In addition, the real-time data tracking feature allows users to see current and historical progress, eliminating the need to manually record results. Kilograms are added or removed instantly and automatically. They will also track calories burned and other statistics to help users maximize their performance. In doing so, the only effort will be physical activity. The Julu dumbbells are made of eco-friendly materials and have an anti-slip handle. Their compact size makes them easier to store than traditional sets. The app also offers the ability to interact with other users for motivation and friendly challenges. One set of dumbbells is being offered on Kickstarter for $239
