Hi, I'm an athlete and lifting heavy weight is also a routine in my daily exercise. I do exercise with my gym partner, and from a couple of days he is facing an issue with his back. For treating the issue he has started to wear weight lifting belt after reading its benefits here https://www.aqfsports.com/blogs/news/definitive-weightlifting-belts-guide , but he is afraid of the actual reason for the pain. Is that occurring due to over stress at his back while lifting weight, or there is an other underlying cause for that pain? Thanks in advance for your suggestions.
