Different ways of holding the bag, the weight of the bag, the length and angle of the belt and the placement of articles all affect the body posture and exertion.

Most importantly, light
The lighter the total weight of the bag, the better. Try not to exceed 10% of the weight, but at most 20%. Relatively thin people need to reduce the burden [1-3″ target=_blank>.
Because no matter how you take it, the heavier the bag, the more crooked your body will be. Not only does the head stretch forward and the body leans forward, but the intervertebral disc in the middle of the spine will also be flattened. These will increase the pressure on the tissues around the spine and the joints of lower limbs, leading to pain everywhere and joint damage [4-6″ target=_blank>.
The backpack becomes heavier, the head stretches forward, and the body leans forward.
If the things you want to bring are too heavy, use boxes instead. Under the same weight, when pulling or pushing a box, the body posture is better than that of a backpack, so it is comfortable and labor-saving, especially if it needs to stand for a long time (the box tie rod is long enough to be pulled straight). But when there are many ramps and steps on the road, it is easier to carry a backpack than a box [7-9″ target=_blank>.

Don’t dislike backpacks, be healthy.
Besides the weight, the way of backpack has the greatest influence on the body. Some people dislike the ugliness of backpacks, but a symmetrical posture on both sides is healthier than one shoulder.
Bilateral is better than unilateral.
When holding it unilaterally, the bag on one side will pull the body away, resulting in scoliosis, high and low shoulders, and uneven stress on the legs, which is prone to joint pain in the head, shoulder and neck, back and lower limbs. For bags with the same weight, changing to double shoulders can obviously reduce these discomfort [4, 10-15″ target=_blank>.

Alternate back and forth, walk behind your back
People often hang their backpacks on their chests for convenience or safety. It’s not easy to hunch over, but it leans back more and puts more pressure on the waist than when you carry it on your back. When the backpack stands for a long time, it can alternate back and forth, but when walking, it is more comfortable to carry it on your back [11, 16-20″ target=_blank>.
