Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, and specifically relates to a sitting chest press trainer for physical training. Background Technique

[0002] A sitting chest press trainer is a fitness equipment specifically used for exercising chest muscles. It mainly consists of a seat, a handle, a weight system and a guide rail. When in use, the user sits on the seat, holds the handle with both hands, and then exercises the chest muscles by pushing the handle. The advantage of this trainer is that it can reduce the participation of muscles in other parts, enabling the chest muscles to be exercised more fully. At the same time, due to its reasonable design, it is safe and convenient to use. Whether it is a fitness enthusiast or a professional athlete, they can improve the strength and endurance of chest muscles by using a sitting chest press trainer.

[0003] The existing Chinese patent (Publication No.: CN208541754U) proposes a sitting chest press trainer, which includes a main support rod and a first base rod, and a rubber backrest is installed on the upper front of the main support rod.

[0004] Through the above technical solution, by providing a fixed rod and a fixed shaft, during the use process, the inclination angle of the power arm hinged to the fixed rod can be adjusted by rotating the fixed rod, thus facilitating the use of the device.
