Detailed ways

In order to make the technical means, creation features, achievement goals and effects of the present invention easy to understand and understand, the present invention will be further described below with reference to the specific embodiments.

In order to facilitate the user to adjust the arm length of the arm strength bar according to their own needs, as shown in Figures 1 to 3, the arm strength training device for physical exercise includes two symmetrically arranged handheld grips 1, two handheld grips 1 phase One side of the back is provided with a movable slot 5 in the middle, and the top of the outer edge surface of the hand grip 1 is equidistantly provided with limit screw holes 8 for connecting to the movable slot 5. The movable slot 5 can be movably installed with an extension. In the handle 10, the inner thread of the limit screw hole 8 is fitted with a limit bolt 9 that can be screwed into the extension handle 10. The handle 10 can be slid in the movable slot 5, so that the length between the extension handle 10 and the hand-held handle 1 can be changed, so as to facilitate the extension of the moment arm when beginners are training arm strength, and the user can adjust the moment arm by himself. The length is beneficial for beginners to gradually adjust the training intensity, and there is no need to buy a weaker arm strength bar separately, which is beneficial to save costs and is easy to use.
