Exercising with a Seton: What You Can Actually Do

Can you work out with a seton in? What's realistic for walking, cardio, and lifting, what to ease back into, and the warning signs to watch for.

You've got a rubber loop threaded through your backside, and your gym bag is sitting by the door. The question is obvious, and nobody at the surgeon's office really answered it. Can you still work out with this thing in?

Short version: usually yes, more than you'd think. This article covers what tends to be realistic with a draining seton in place, what to ease back into, and what to watch for. I've worn setons twice, months at a time, and kept training through most of it. Here's how that actually went, plus the common-sense stuff that applies to most people.

Important: This content reflects personal experience and community-sourced tips, not medical advice. Every fistula case is different. Always discuss treatment decisions with your colorectal surgeon or gastroenterologist. What worked for one person may not be right for your situation. Your surgeon may also have specific restrictions based on your procedure, so clear it with them first.

Can You Exercise With a Seton In?

A seton is a thin loop of material, usually silicone or surgical suture, that your surgeon threads through the fistula tract and ties loosely. A draining seton (the most common kind) sits there to keep the tract open so it drains instead of building into an abscess. It is not healing anything on its own. It is holding the line while you wait for the next step.

Here's why that matters for exercise: the seton is designed to stay put while you live your normal life. It is not delicate. It does not pop out if you break a sweat. Once the initial soreness from placement settles, usually a couple of weeks, most people can get back to moving.

The catch is that "moving" covers a lot of ground. Walking and a heavy leg day are not the same ask. So let's go activity by activity.

Walking: Start Here

Walking is the safest place to restart, and it is genuinely useful. It keeps blood moving, helps your bowels stay regular (which matters more than you'd think when you have a wound in that area), and it does not stress the site.

For the first week or two after placement, short and frequent beats long and ambitious. A few ten-minute walks a day is plenty. You are testing how the area feels, not training for anything. If walking feels fine, it almost always does, you build from there.

Cardio and What HIIT Actually Feels Like

Once walking felt like nothing, I went back to cardio, including HIIT. That surprised me. I expected the jumping and the constant up-and-down to be a problem. It wasn't.

The thing to understand is that your seton is anchored in a loop. General movement, sweating, bouncing, none of that dislodges it. What you might notice is more awareness of the area during high-impact work, and a bit more drainage afterward from the activity and the sweat. That is normal. It is not a sign you broke something.

Pro tip: Sweat plus a draining wound means hygiene matters more on training days. A rinse or a quick sitz bath after a hard session keeps irritation down. (More on that in Keeping Clean With a Seton.)

Lifting: What I Kept and What I Dropped

I kept lifting through the whole thing, with one change. I dropped heavy squats.

Here's the reasoning. Most lifts were fine. Pressing, pulling, upper body, moderate lower body, none of it bothered the area. But heavy squats load you in a way that ramps up pressure straight down through the pelvic floor and the site. That extra pressure is the kind of thing that can make a draining wound complain. So I either went much lighter on squats or swapped them for movements that hit the legs without that same downward load.

This is a common theme people land on: it is not lifting that tends to cause trouble, it is the specific movements that spike pressure in that region or grind directly on the seton. Heavy squats and heavy deadlifts are the usual suspects. Plenty of people lift around them without issue by going lighter, slowing down, and skipping the grinding max-effort sets while the seton is in.

Pro tip: If you're going to lift, breathe through the reps. Holding your breath and bearing down (the classic heavy-lift grunt) is exactly the pressure spike worth avoiding while you have a seton in.

Listen to Drainage, Not Just Pain

This is the part that took me a bit to understand. With a normal injury, pain tells you when to stop. With a seton, drainage is also a signal worth reading.

A little extra drainage after exercise is expected, especially with sweat involved. What you are watching for is a real change: a noticeable jump in drainage that does not settle, new pain that lingers into the next day, increased swelling, redness, or heat around the area. Those are signs to back off and, if they stick around, to check in with your surgeon.

If you feel good during a session and the area is calm the next morning, that's your green light to keep going.

A Few Practical Things That Help

None of this is groundbreaking, but it makes training with a seton less of a hassle:

Moisture-wicking, snug-but-not-tight underwear. It keeps the area dry and limits the seton catching or rubbing during movement. Cotton holds sweat and stays damp, which is the opposite of what you want.
A change of underwear in your bag. On heavy-sweat or heavier-drainage days, swapping out post-workout keeps you comfortable and clean.
Time it around your bathroom routine. Training after a bowel movement and a rinse, rather than before, tends to feel cleaner and lets you skip mid-session surprises.
A small pad or gauze if drainage picks up with activity. Some people use a thin liner on heavier days so they're not thinking about it during a set. A common approach, not a requirement.

When to Back Off

Most of the time, your body makes the call clear. Stop or scale back if you get a sharp increase in pain at the site, drainage that changes in a way that worries you, signs of a possible abscess (a hot, swollen, increasingly painful lump), or a fever. Any of those means it is time to rest and call your surgeon, not push through.

And right after a procedure, follow whatever timeline your surgeon gives you over anything you read here. Fresh placement, a recent flap, or any new surgery resets the clock.

The Part Nobody Mentions

There is a mental side to this too. Getting back to training while you have a seton in is not only about fitness. It is one of the few areas of fistula life where you still get to feel normal and capable, where the condition isn't running the show. That matters more than it sounds like it should. If the head stuff is wearing on you, that's covered in The Mental Health Side of Fistula Recovery.

The bottom line: a seton is not a reason to stop moving. For most people, it is a reason to adjust a couple of things and carry on. Start with walking, build back to cardio, keep lifting but be smart about the movements that spike pressure, and let drainage be part of how you read your limits.
