What is EWOT (Exercise with Oxygen Therapy)

EWOT (Exercise With Oxygen Therapy) is a powerful training method that combines light-to-moderate exercise with high-concentration oxygen. By breathing elevated levels of oxygen during movement, your body can increase energy production, improve circulation, support cellular health, and enhance overall recovery and longevity.

Whether you’re an athlete, focused on anti-aging, or simply want more daily energy, a quality EWOT system makes this therapy simple and effective at home or in the clinic.

EWOT Research and Benefits

Backed by Science: The Power of EWOT

​

German researcher Dr. Manfred von Ardenne, a pioneer in oxygen therapy, identified why our energy declines with age: a physiological drop in the body’s ability to utilize oxygen efficiently. His groundbreaking work, detailed in Oxygen Multistep Therapy: Physiological and Technical Foundations, cites over 500 medical references and draws on 10,000 studies to demonstrate how Exercise With Oxygen Therapy (EWOT) can reverse this decline. By delivering high-flow oxygen (8-10 liters per minute at 90-95% purity) during exercise, EWOT enhances cellular oxygen uptake, helping you reclaim youthful energy and vitality.

​

Proven Benefits of EWOT

Von Ardenne’s research highlights seven key benefits of EWOT, each supported by science to improve overall health:

​

1. Boosts Oxygen Circulation
   Inadequate oxygen supply is linked to many chronic conditions. EWOT floods tissues with oxygen, supporting cellular health and reducing disease risk.

2. Restores Blood Flow
   Enhanced circulation optimizes the function of every bodily system, from the heart to the brain, promoting overall wellness.

3. Increases ATP Production
   Oxygen fuels ATP, the body’s energy currency, powering cells for improved stamina and vitality.

4. Enhances Physical Performance
   Athletes and active individuals experience improved endurance and recovery with regular EWOT sessions.

5. Reduces Inflammation
   Increased oxygen levels help lower systemic inflammation, easing symptoms of chronic conditions.

6. Supports Weight Loss
   By boosting metabolism and energy, EWOT aids in fat burning and weight management when paired with exercise.

7. Promotes Detoxification
   Enhanced oxygen delivery supports the body’s natural detox processes, flushing toxins and improving organ function.

Considerations when purchasing an EWOT System

To obtain the benefits of EWOT the German research was very precise regarding the conditions under which EWOT should be performed. That is, you will require: An oxygen source that produces a high flow of oxygen of at least 8 - 10 liters per minute, a purity of Oxygen at 90 – 95%. Do not be tempted to purchase the smaller, lower flow, lower purity oxygen concentrators that are now available from China and some North American and European resellers. These small oxygen concentrators typically produce only 2 to 3 liters per minute at a purity level of only 30 – 50%. One must also be careful to avoid the use of a standard oxygen concentrator that produces 5 Liters per minute, which just happens to be the most common oxygen concentrator on the market. These 5 Liter per minute models are fine for those patients who are either housebound or wheel chair bound due to the fact that they are not exercising. However, the original German research shows that 5 Liters Per Minute is insufficient to provide the benefits of EWOT.

Not only is 8 - 10 Liters per minute required, but the person seeking to obtain the benefits of EWOT will also need to be wearing an EWOT Mask. This is an oxygen mask that has a bag attached to it. The bag catches the oxygen that would otherwise be lost when you are exhaling. (See Photo of the On-Demand EWOT Mask here: On Demand EWOT Mask.  Since this oxygen is caught by the bag and not lost, you are able to breathe it in on the next inhalation. This is the only way that you will be able to breathe all of the oxygen that is made by the oxygen concentrator. A standard oxygen mask, nasal cannula (nose hose), or an aviator style headset will simply not work because the oxygen produced by the oxygen concentrator is lost to the air when you are exhaling. You may also use a reservoir bag which you prefill before exercising. In this case you will use a mask will only allow you to breathe oxygen from the reservoir bag, (See Photo of the O2Max EWOT Mask: O2Max EWOT Mask. Optimize Products provides both systems, and a combination of the two for just $160.00 more, as you will see at the bottom of the page.​​​​​

​

Optimize Products is the only Company in the marketplace that provides both an On-Demand EWOT System and a Reservoir EWOT System.

In just one package, you’ll receive BOTH of these systems at an extremely competitive price.

Before continuing, we should explain the main difference between “Standard On-Demand EWOT” and “Reservoir EWOT”:

• Standard On-Demand EWOT is when you exercise on stationary exercise equipment while breathing oxygen from an oxygen concentrator through a very specialized EWOT mask, as well as some room air. German researchers a few decades ago proved that there are tremendous benefits from Standard EWOT, but we’ll get to that information later.

• Reservoir EWOT is when you exercise on stationary exercise equipment while breathing oxygen from a bag full of oxygen, or an “O2 Reservoir,” again by using another special (and yet different) mask. In this case you are not breathing any room air at all, just purified oxygen.

So our Dual Reservoir & On-Demand EWOT System provides you with the ability to perform both “EWOT” and “Super Reservoir EWOT”! This is the only system of its kind in the USA.

You might be wondering, “…why would I want to have access to both of these systems?”, or “…what is the advantage to that?”. I’d be happy to explain….

The challenge with “Reservoir EWOT” is that it takes time to fill the O2 Reservoir Bag with oxygen, usually 90 to 100 minutes if you are using a 10 liter oxygen concentrator. It is simple math. The bag is 1000 liters and the 10 liter oxygen concentrator produces 10 liters of oxygen per minute. Divide 1000 liters by 10 liters LPM which equals 100 minutes. When you are comparing products on the market keep this in mind, as many companies do not share this information. So what? Well, let’s say you overslept. You have a meeting coming up, you are late and you are rushed, but you really want to get your EWOT workout in before leaving for work to ensure you are sharp and on your game. You want to perform  "Reservoir EWOT” but you don’t have time to fill the reservoir bag with oxygen.

Good news!!… Your Dual Reservoir & On-Demand EWOT System comes with all of the equipment you need to perform ‘Standard’ On-Demand EWOT too. Just turn on the oxygen concentrator, put on the special On-Demand EWOT Mask (which is the key to this unique system), jump on your exercise machine for 15 minutes, and you are done, and on your way to your meeting. Yes, it’s all over in just 15 minutes! …and Yes, you receive tremendous benefits from that “Standard” EWOT Exercise, but only because the Dual EWOT System comes with the specialized On-Demand EWOT Mask that you need to make this work for you!

The next day you arise, and you have plenty of time to fill the O2 Reservoir Bag for EWOT. You take your time, fill the bag, and when the bag is full of Oxygen you exercise on your favorite stationary exercise equipment and head off to the shower feeling great.

Saturday morning, you have lots of time, so you want to perform a 1-hour workout and breathe oxygen the entire time. In this case, no “O2 Reservoir EWOT system in the world would work for you because it would be depleted of oxygen in between 15 and 30 minutes based on averages. So, in this case, it would be best if you performed “Standard” EWOT for the duration of the workout with a special ‘Standard’ EWOT Mask. Again, your Dual Reservoir & On-Demand EWOT System is the only system on the world market that provides you with the proper On-Demand EWOT mask to make this work for you.

Here’s the point….

Depending on how much time you have each day, you’ll benefit from either using On-Demand EWOT or Reservoir EWOT. However, there is no other system on the world market other than the Optimize Dual Reservoir & On-Demand EWOT System that can provide you with the capability to use both EWOT Techniques.

1. The “Standard” EWOT companies don’t provide the proper mask even for EWOT, let alone the accessories necessary for “Reservoir EWOT”.

2. The “Super EWOT” companies sell against “Standard On-Demand” EWOT because they don’t have the mask necessary to make Standard EWOT work for you.

The ultimate answer is the Optimize Dual Reservoir & On-Demand EWOT System, which provides you with the unique ability to choose to perform “Standard EWOT” or “Reservoir EWOT”, whichever one suits your requirements on that day.

One final question….Does “Standard On-Demand” EWOT Really work? Yes, it does! Here’s how we know….

The reality is that a German researcher, Dr. Manfred von Ardenne (referred to above), proved that with the proper EWOT Mask and Oxygen Concentrator, “Standard” EWOT provides tremendous benefits even if you just perform it for 15 minutes per day. But only if you use the proper EWOT Mask, like the On-Demand EWOT Mask you’ll receive in your Super EWOT System Package. It just so happens that the On-Demand EWOT Mask is an exact duplicate of the EWOT Mask used in von Ardennes research, and therefore proven to work.

Now, not only do you not have to choose between “Reservoir EWOT” and “On-Demand EWOT”, you have reasons to perform both and enjoy the benefits of both! And only our Dual Reservoir & On-Demand EWOT System can provide you with both, in one System Package, and at one extremely competitive price!
