The muscles that require anal training are the anal sphincter muscles, which are a little over an inch inside your butt. Both the internal and external sphincter muscles form a ring around the anus, and their primary function is to prevent you from unexpectedly farting and shitting yourself.
Kind of like when you lift too heavy at the gym and your muscles are sore the next day. The anal sphincter, like all muscles, requires training to perform at their best.
Only instead of lifting weights, anal training uses toys and penises to stretch the muscles and help them relax for penetration. And instead of progressing toward heavier weights, the goal of anal training is often to progress toward larger sizes.
Not only does anal training help the muscles relax, it also allows for skin elasticity and toughness courtesy of the friction and continual stretching involved with anal training. Both factors will also help prevent injury. As a concept, anal training is simple. Start with a small toy, and gradually work your way toward larger sizes as your body gets comfortable.
Anal training usually takes anywhere from four to six weeks, with each dilation session lasting about three to five minutes. Stick with each toy for roughly two weeks. Though you will likely feel that you can upsize earlier, you want the muscle memory to understand relaxation.
