Brand: Bouboumise Color: Green Material: stan Arm Bar Manufacturer: Arm Bar Beginner An arm bar is a training tool primarily used to train the pectoral muscles. There are bar-shaped arm bars and pressure-type arm bars, and the load varies depending on the gender. Arm bars apply load mainly to the pectoral muscles by pushing the arms inward. Bench press is representative for training the chest, but it is difficult to install at home, so it is better to use an arm bar. The pectoral muscles are "difficult to train" muscles, so the AORTD arm bar is effective. Also, for women, it can help with bust-up and prevent sagging breasts, so it's a good idea to have one. If you want to apply a load like an arm bar with dumbbells, you would have to buy adjustable dumbbells that cost around 20,000 yen. However, if you use a hydraulic arm bar, you can achieve a high load of nearly 200kg, allowing you to train efficiently. It is possible to build chest muscles faster than with dumbbells or push-ups. If you want a masculine chest, buy one first. Also, for women, it has the effect of bust-up and preventing sagging breasts by training the pectoral muscles. 【Product Specifications】Note: Please refer to the instruction manual when you receive the product.
