Review on LEADNOVO Adjustable Weights Dumbbells Barbell Set - 3 In 1 Home Fitness Weight Training For Men & Women by Danny Kamerer

Pros: These weight sets are excellent in that it can turn into dumbbells or barbell at any time. The assembly is straightforward. Octagon shapes also help the weights to stay in position.Cons: Pretty obvious, but since you have to assemble to make it dumbbell or barbell, you have to disassemble & resemble each time if your training requires a mixture of dumbbells & barbell. Also, dumbbells will have metal bars protruding to the sides when assembled, so be mindful of this if you're thinking of doing barbell weight-trainings.
