This expander is an ideal option for fully working out the back muscles. As you know, for a swimmer, the back muscles are one of the most important. When rowing during swimming of any style, the main load almost always falls on the back muscles, so working them out is one of the main tasks during training on land. An expander from Nike allows you to load your back very well. It is better for swimmers not to overuse weight training in the gym, while the load from the expander does not clog the muscles and allows them to maintain speed and increase endurance. This is why Proswim.ru recommends using an expander to work out your back muscles, rather than dumbbells and a barbell. Training with the Figure resistance band from Nike is very comfortable. The handles are covered with soft material, so you won’t have calluses after training. Among the advantages of this trainer from Nike are its small size and light weight. This allows you to easily transport it, which is very convenient if you want to keep fit while on vacation or traveling.
