Standing up shouldn't feel like running a marathon. But for people living with Postural Orthostatic Tachycardia Syndrome, that’s basically the daily reality. Your heart races, your head swims, and suddenly the floor looks like a really inviting place to nap. It’s frustrating because the standard medical advice—"just exercise more"—often feels like a cruel joke when walking to the kitchen leaves you gasping.
Honestly, most generic gym routines are a disaster for POTS. If you jump into a high-intensity interval class or try to grind out miles on a treadmill, you aren’t just "working hard." You’re likely triggering a massive sympathetic nervous system flare that will leave you bedbound for three days. To get better, you have to stop thinking like an athlete and start thinking like a physicist. It’s all about gravity.
The Levine Protocol and why "horizontal" is your new best friend
Most people think an exercise program for POTS syndrome needs to look like a standard fitness journey. It doesn't. Dr. Benjamin Levine and his team at UT Southwestern basically rewrote the rules for this. They realized that if your heart is struggling to pump blood upward against gravity, the smartest move is to simply remove the gravity.
Start on the floor.
Recumbent exercise is the foundation. We’re talking rowing machines, recumbent bikes, or even swimming. When you are horizontal or seated with your legs out, your heart doesn't have to fight nearly as hard to keep your brain oxygenated. This allows you to actually build cardiovascular volume without the "gray-out" feeling of pre-syncope.
I’ve seen people try to skip this phase. They feel a little better after a week and try to go for a jog. Big mistake. You need months—not weeks—of base-building in a reclined position before your stroke volume increases enough to handle standing up for long periods.
Why your blood volume matters more than your "gains"
POTS isn't just a heart problem; it's a "pipes" problem. Your veins don't constrict quite right, so blood pools in your legs. A solid exercise program for POTS syndrome focuses on two things: increasing the total amount of blood in your system and building the "muscle pump" in your lower body.
Think of your calves as your second heart.
When you strengthen your gastrocnemius and soleus muscles, they help squeeze blood back up toward your chest. This is why "leg day" is actually more important than cardio for many POTS patients. But again, don't do standing squats yet. Try leg presses, seated calf raises, or floor-based resistance band work.
The salt and water trap
You cannot exercise your way out of a dehydrated state. Dr. Blair Grubb, one of the foremost experts on dysautonomia, often emphasizes that lifestyle triggers are the "fuel" for POTS flares. If you’re starting a new workout routine, you probably need to double your salt intake.
I’m serious.
Many POTS patients are told to consume 5,000 to 10,000 milligrams of sodium a day. That sounds insane to a healthy person, but for someone whose body dumps salt, it’s a lifeline. If you try to sweat during a workout without a massive surplus of electrolytes, your blood volume will drop, your heart rate will skyrocket, and the workout will fail. Drink a liter of water with electrolytes before you even touch a piece of equipment.
Heart rate zones: Stop chasing the burn
In a typical workout, a high heart rate is a badge of honor. In a POTS workout, it can be a warning sign. You want to stay in "Zone 2" for a long time. This is the "conversational" pace. If you’re gasping, you’ve gone too far.
Use a chest strap heart rate monitor. Wrist-based ones are notoriously flaky for POTS patients because of poor peripheral circulation. Watch for the spikes. If you see your heart rate jump 30 beats for no reason, stop. Lie down. Put your feet up on a wall. Wait for the "tachy" to subside before you continue.
The "push-crash" cycle is your biggest enemy
There’s this toxic idea in fitness that you should "push through the pain." If you do that with dysautonomia, you will lose. Period.
POTS involves a sensitive nervous system. If you overreach, you trigger a "crash" known as Post-Exertional Malaise (PEM), which is also common in Long COVID and ME/CFS. This isn't just being tired. It’s a systemic shutdown.
- Week 1-4: Focus entirely on floor stretching and 5-10 minutes of recumbent cycling at zero resistance.
- Week 5-8: Increase to 15-20 minutes. Add seated strength training.
- Week 12+: Only now do you consider upright activity, and even then, start with just a few minutes.
Consistency beats intensity every single time. It is better to do five minutes of movement every day than 30 minutes once a week that leaves you shattered.
Real talk about compression gear
You'll feel like a 1920s diver, but medical-grade compression is a game changer for your exercise program for POTS syndrome. We aren't talking about those cheap "athletic" socks from the drugstore. You need 20-30 mmHg or even 30-40 mmHg waist-high stockings.
By compressing the abdomen and the legs, you prevent the blood from pooling. This keeps your "effective" blood volume higher, which means your heart doesn't have to beat as fast to do the same amount of work. Some people find that wearing a tight abdominal binder during exercise is the only way they can get through a session without fainting. It’s not about aesthetics; it’s about hemodynamics.

Temperature matters more than you think
Heat is a vasodilator. It opens up your blood vessels. For a POTS patient, this is a nightmare.
If your gym is at 75 degrees, you’re going to struggle. Try to work out in a cool environment, use a neck fan, or sip ice water throughout. Many people find that "pool therapy" or swimming is the ultimate POTS exercise because the water acts as a giant compression suit and keeps the body temperature regulated simultaneously.
Why some days you just can't
There will be days when your "morning orthostatic heart rate" is already 120 just from brushing your teeth. On those days, don't follow the plan.
Listen to your body.
If you’re in a flare, "exercise" might just mean doing some gentle ankle pumps in bed or squeezing your glutes while lying down. This still counts. It keeps the blood moving without overtaxing the adrenals. The goal of an exercise program for POTS syndrome is long-term remodeling of the heart and nervous system, not a six-week transformation. It took time for your system to become deconditioned or dysfunctional; it will take time to move the needle back.
The role of Beta-Blockers and Ivabradine
Sometimes, the nervous system is just too "loud" to allow for exercise. If your resting heart rate is consistently too high to even start a recumbent bike, talk to your cardiologist. Medications like Propranolol (a beta-blocker) or Ivabradine (a funny-channel blocker) can "lower the ceiling" on your heart rate.
This isn't "cheating." These meds can provide a pharmacological window that allows you to actually perform the exercise needed to get better. Think of them as training wheels. They stabilize the heart so you can build the muscle and blood volume necessary to eventually (hopefully) need less medication.
Actionable steps to start today
Don't wait until you feel "perfect" to start, because with POTS, that day might not come for a while. Instead, start tiny.

- Measure your baseline: Check your heart rate lying down, then after standing for 10 minutes. This is your "Poor Man’s Tilt Table" test.
- Salt up: Increase your sodium intake (under doctor supervision) and see if your standing heart rate drops. If it doesn't, exercise will be ten times harder.
- Find a "Low" machine: Go to a gym and find the recumbent bike. Sit as low as possible.
- The 5-Minute Rule: Commit to just five minutes of very slow pedaling. If you feel okay, do it again tomorrow. If you feel like death, wait two days and try three minutes.
- Focus on the "Big Three" lifts: Seated leg press, leg curls, and calf raises. These build the muscles that fight gravity.
- Log everything: Use a journal to track your salt, water, sleep, and exercise. You’ll start to see patterns—like how a bad night’s sleep makes your "easy" workout feel impossible.
The road to recovery with POTS is rarely a straight line. It’s more like a jagged mountain range. You’ll have weeks where you feel like an athlete and days where you feel like a Victorian ghost. That’s okay. The secret isn't intensity; it's the refusal to stop moving, even if that movement is happening while you're lying flat on your back on a yoga mat. Keep the blood moving, keep the salt flowing, and give your body the time it needs to recalibrate.
