The principle of Felix stick is to stimulate your deep muscles based on the vibration principle, so that you can quickly increase your heart rate in the shortest time, thus achieving the effect of reducing fat and shaping. It can train upper body muscles and strengthen your core strength, which is also quite beneficial to the toughness of your arms.

I have used this tool, and it feels good. After using it for a minute or two, I sweated and my arm ached. It is quite suitable for athletes who don't have much exercise time. As a light sport, it can effectively improve their physical fitness. I also bought one at home, and sometimes my wife and parents use it to exercise.

If you don't have time to go to the gym, you can buy one for training at home as a light exercise, with a score of 10 every day. This fitness stick is very convenient to use at home, does not disturb others, does not need much space, and can also strengthen hand muscles well. When exercising, I feel that the core muscles are also exerting strength, and the effect is unexpectedly good.
