Exercises to strengthen and tighten your anal sphincter may help treat bowel incontinence fecal incontinence or reduce your chance of leaking stool or gas in the future. And not unlike these other muscles, the muscles that control your bowel can be strengthened through exercise. While the internal anal sphincter is not under conscious control, the pelvic floor muscles that form an external band of muscle around the anus are readily strengthened through relatively simple exercises. Knowing the muscles that control your anal sphincter and how they work makes understanding the exercises much more clear. The internal anal sphincter is an involuntary muscle, which means you cannot consciously control it. The internal sphincter is programmed to stay shut, which is why most adults do not leak stool while they sleep.
