Futuristic Magnetic Dumbbell Concept
What is the worst part of weight training? Some might argue that it is the weights themselves. However, traditional dumbbells may soon become a thing of the past. The future is now molded by the concept of electromagnetism or so says the O2 Magnetic Dumbbell. The two small rings worn by the user above and below the elbow are powered by embedded electromagnets that provide a push and pull resistance.
