Technical Field

The invention relates to the technical field of fitness equipment, and in particular to a strength type bench press training device and a use method thereof.

Background technique

The bench press is one of the most common and effective methods for developing chest muscles. When performing strength training, the weight of the bench press is usually increased to the trainee's maximum weight. Therefore, a coach is required to supervise during strength bench press training to prevent the trainee's bench press lever from falling. Once the trainee's bench press lever falls, the trainee will be injured, so the safety effect is not good. In addition, the lever needs to be reset after the trainee loses strength, which is extremely strenuous for the trainee after training and inconvenient to use. Therefore, we propose a strength bench press trainer and a method for using the same.
