The dumbbell is a must-have tool for bodybuilders who value their ease and effectiveness. First of all, it gives an all round workout. More than one muscle group can be exercised simultaneously in this way. Secondly, it is extremely flexible. People who use it can do anything from simple movements like rows or presses to more complicated ones such as squats and push-presses. It's all this flexibility that makes sure you'll keep making progress and won't bench yourself (so to speak). What's more, dummbells are compact and easily stored, making them a perfect choice for the home gym. Plus they develop balance and coordination since each arm works on its own. Plus, using dumbbells can also increase bone density and improve joint health. This contributes long-term health benefits to the fortunate user. Last of all, compared to other gym equipment, dumbbells are cheap. This strengthens people like me who cannot afford a gym membership/have no access to one.
