STRENGTH TRAINING DEVICE

Description

1. TECHNICAL FIELD

The invention relates to the technical field of fitness equipment, in particular to a strength training device.

2. BACKGROUND ART

Strength training is an exercise method that improves the strength, endurance and shape of muscle groups through multiple sets of rhythmic weight-bearing exercises. Strength training is mainly anaerobic exercise, such as weight-bearing squats, push-ups, barbell rowing and other exercises. However, we can combine the advantages of aerobic exercise with light weight, multiple times, and multiple sets of circular exercises, which can decompose and utilize the lactic acid produced by anaerobic metabolism again to reduce muscle discomfort.

In a traditional strength training device, one end of the sprocket is connected to a handle bar, and the other end is connected to a weight plate; during training, the weight plate is pulled up by applying downward pulling force to the handle bar.
