PowerBlock Pro 50 Adjustable Dumbbells, Sold in Pairs, 5-50 lb. Dumbbells, Durable Steel Build, Innovative Workout Equipment, All-in-One Dumbbells

PowerBlock Pro 50 Dumbbells are advertised as expandable, but according to the company's website, they are not expandable. Some customers have reported that they have been able to expand the weight up to 90lbs, while others confirm that it has an increment limit of 50lbs. Nevertheless, the equipment is well built and comes with adjustable weights, and it requires little space, making it ideal for home exercises. Some customers have reported issues such as delivery of only one side, broken components, and difficulty getting customer support to rectify the problem. The company has an excellent full-body workout video by Clark Bartram that educates users on using the dumbbells. However, the product is expensive, and those who only need weight increments of 50lbs will find it sufficient. The equipment can work with expansion weight, and there are testimonials from satisfied customers.
