The Bana Bender is a concept/gadget following the idea to integrate exercise with taking a shower. This simple device allows you to work on your upper-body and take a shower at the same time. Great concept or stupid gadget? We’ll let you decide. The Bana Bender actually replaces you shower nozzle and water will be coming out of it as you exercise! If everything goes according to plan, you should start sweating just when you are done showering.
