Gym pull-up resistance band

Why is the length of Gym pull-up resistance band usually 208cm? 

I.Meet the needs of most people: The length of 208cm can be used by people of different heights and arm lengths. Whether it is a standard pull-up or other related training movements, it can provide enough length to produce appropriate resistance and auxiliary effects.

II.Adapt to a variety of training methods: Such a length can be easily fixed on a crossbar of different heights to adjust the strength of the assistance, and it can also meet some specific training movements that require longer straps.

III.Easy to carry and store: The length of 208cm is relatively moderate, neither too long to cause inconvenience in carrying, nor too short to limit the flexibility of use.

However, it should be noted that not all pull-up auxiliary straps are 208cm, and there are actually products of other lengths. When choosing an auxiliary strap, in addition to the length, you also need to consider factors such as its material, elasticity (the amount of resistance provided) to ensure that it meets your personal training needs and ability level.
