You may often see this yellow TRX sling on the ceiling of the gym. Many people don't understand what it is for. This seemingly simple sports equipment is very popular in developed countries. It uses people's own weight to help trainers complete almost whole body muscle training and improve strength, flexibility and core stability.

TRX sling is mainly composed of sling, training stick, main rope, handle and anklet. As long as you find a hanging point, you can become a fitness place at home, dormitory or outdoors. There are all kinds of movements, and sometimes you need to stand firm, so you need to wear shoes to protect your feet.
