Two of the most frequent questions we get are, “How are the Marc Pro and Marc Pro Plus different?” and “Which one should I get?” Both devices use our patented technology to deliver the most effective results. However, there are a few key differences between the two.

marc pro vs. marc pro plusWhat is the Marc Pro?

Recovery, Conditioning, and Performance

The Marc Pro creates non-fatiguing muscle contractions, meaning you can use the device for as long as you need to ensure a full recovery. By improving the recovery process, you can prevent overuse injuries, perform better, maintain proper biomechanics, reduce soreness/fatigue, train or play more often, maximize training results, and operate at your full potential. Marc Pro can also be used as a warm-up tool to loosen up muscles. Plus, using Marc Pro consistently is shown to improve vascular capacity (conditioning), so your muscles can do more and last longer before they break down again. The Marc Pro achieves all of these benefits in one comfortable, easy-to-use setting and is set at 2Hz.

Where can I use it? Marc Pro can be used to target any muscle group.

What is the Marc Pro Plus?

marc pro vs. marc pro plusRecovery, Conditioning, Performance & Pain Relief

The Marc Pro Plus offers all the benefits of the standard Marc Pro on the LOW setting (2Hz). The main difference is that this device also offers an additional HIGH setting (60Hz) which is used to provide very significant and lasting pain relief. The HIGH setting will make you feel substantially better but does not have the rehabilitative benefit of the LOW setting. This setting is designed for more intense nerve-related pain, as opposed to muscle soreness which can be addressed with the LOW setting. Also, the HIGH setting feels much different from the LOW setting. Users will feel a strong, yet comfortable buzzing sensation instead of muscle contractions.

Where can I use it? The LOW setting on Marc Pro Plus can be used to target any muscle group. The HIGH setting can be used to target pain in the knees, ankles, shoulders, back, neck, hips, elbows, and wrists.

*The Marc Pro Plus can also be put into manual mode allowing users to select their own frequency between 1-70Hz.

Which is Right for Me?

Marc Pro: If your goal is to enhance recovery, elevate performance, eliminate soreness/fatigue, prevent overuse injuries, and improve conditioning.

Marc Pro Plus: If you are dealing with pain that is beyond muscle soreness or if you like to experiment with new protocols and applications (for example, Brian Mackenzie shows how to use the Marc Pro Plus to release tight, locked up muscles). If you want the ability to shut down pain as well as enhance recovery, elevate performance, eliminate soreness/fatigue, prevent overuse injuries, and improve conditioning.

release musclesWhen tissue is really banged up, it may take a while for the low frequency setting of the Marc Pro Plus to flush out the area, loosen everything up, and bring the body back to homeostasis. Brian Mackenzie shares an alternative approach that can provide much faster results. With intense and consistent workouts or activity, muscles will often shorten and lock up. Knots, spasms, limited range of motion, and many other issues can then set in. Sometimes, to get a damaged area back on par with the rest of the body, we first need to get that muscle tissue to release.

Unlike the LOW setting, the HIGH setting on the Marc Pro Plus will actually fatigue muscles. For recovery purposes, this isn’t ideal. However, when it comes to releasing locked up tissue, it’s very beneficial. As the electric current is fired into the muscle, the motor neurons get stimulated and the fibers start to contract. After some time, the motor neurons give up and the tissue releases.

How to Use HIGH Frequency to Release Muscles

  1. Place electrodes on the muscle group you want to target
  2. Set your Marc Pro Plus to the HIGH setting
  3. Slowly turn up the intensity to a level that feels strong, yet comfortable
  4. Leave the unit on until the muscle relaxes – this may take a minute but you will be able to feel when the tissue releases
  5. Once the muscle releases, turn the unit off

After the muscle releases, there may be a little soreness from all the muscle fibers that were being fired. When using HIGH frequency for this application, more muscle fibers are being contracted than would be by independently doing this. Muscles you don’t usually use are going to be recruited so there will be a little more damage than normal.

How to Use LOW Frequency to Recover Muscles

Once you get the muscle to release, use the LOW setting of the Marc Pro Plus to recover the area and get rid of the soreness. Now that the muscle is relaxed, the LOW frequency can be used to bring the muscle tissue to a full recovery.

Brian Mackenzie has used this alternative protocol to relieve a lot of debilitating tissue damage. It’s a great way to lengthen muscles for an increased range of motion as well as getting rid of knots, spasms, or other areas where the tissue is shortened, tight, and locked up.

Electronic Recovery: A Shocking Option for Outdoors Athletes

Gear Junkie writer and professional adventure racer, Chelsea Magness, recently put Marc Pro Plus to the test. At first, Chelsea was skeptical the device would help her, but since she kept hearing the benefits other athletes had experienced, she decided to at least give it a try. After 5 months of testing the Marc Pro Plus, she wrote her review for Gear Junkie.

“I noticed it the most after long travel days. Sitting on a plane or in a car for hours at a time makes my legs and back feel heavy. It usually takes me a full day of walking around and going upside down to get the blood and lymph to cycle through.

However, after a 30-hour travel stint, I had no swelling or “lead” feeling in my legs. Most recently, I have been using it in between workouts on my double days. For example, I will go skiing in the morning then come home and use it on my legs or arms for 30 min; in the afternoon I will go and do a pack run interval or bike ride.”

active recoveryThe Marc Pro and Marc Pro Plus will allow you to recover more effectively than normal through traditional active recovery techniques; however, when looking at the unit, you may be wondering, “What happens if I crank this button up all the way on high? What happens if I raise the intensity? When is it better to keep the intensity lower?”

The experts at Marc Pro have the answers so that you can get the maximum benefit out of your Marc Pro or Marc Pro Plus for your specific needs.

Using the Marc Pro for Better Recovery

Generally speaking, higher intensity levels yield better and faster results. The reason is simple: more intensity translates to stronger muscle contractions. This means that you’re pumping out more waste (i.e. damaged tissue) and bringing in more nourishment (i.e. oxygenated blood) to the area being targeted. (if you remember one thing from this post, think “Waste Out, Nourishment In.”)

However, if the contractions are causing any type of discomfort or pain, the raised intensity could be causing more harm than good. In this situation, intensity levels should be reduced. Also, if the strength of the contraction doesn’t allow you to relax and you find yourself resisting the muscle activity, you should also reduce the intensity.

Using the Marc Pro Plus for Pain Relief

With the Marc Pro Plus, you need to choose what frequency (mode) to use before cranking up the intensity. Low Frequency is the setting of the standard Marc Pro. This is where all of the recovery and conditioning benefits come from. Low Frequency contracts muscles to flush out waste and deliver nutrients to the area. If pain or soreness is related to a lack of recovery or to a buildup of congestion, then Low Frequency is the setting to alleviate those issues.

On the other hand, if you are experiencing aches and pain that seems to be more related to an irritated nerve as opposed to a lack of muscle recovery, then the High Frequency mode of the Marc Pro Plus is the way to go. There are no muscle contractions in this mode as the objective of the strong, yet comfortable stimulus is to directly calm down irritated nerves and shut down stubborn pain related to your sport or activity.

After shutting down pain with the High Frequency Mode, you will typically want to still flush and help that area recover using the Low Frequency setting. In some cases, you can use the two settings simultaneously (e.g. one channel is using High Frequency directly through the knee joint to calm down that area while the other channel is simultaneously contracting the quad and calf muscles to move nourishment and waste).

When using the High Frequency Mode, stronger intensity levels yield longer lasting pain relief, without the use of over-the-counter drugs or side effects. The intensity level should be turned high enough to eliminate the sensation of pain during the session. By continuing to work the intensity level up higher throughout the session, you’ll feel the most significant results. As with Low Frequency, the signal may feel strong and intense, but should never be raised to a level that causes pain or discomfort.

Being able to control the intensity levels associated with the Marc Pro allows you to customize your recovery to ultimately deliver the best individual results.

“This is just one of the many tools we’ve used with the Marc Pro Plus especially on that high setting in order to set things in place or get the stimulus that we need in order to make the mechanical changes that we want and it’s a great tool in doing that.”

Swim to Run recently did an in-depth review of the Marc Pro Plus.  They looked at everything from the specs on what’s included in the box to their own experiences with the device.  Read the full Marc Pro Plus review here.

“Using the low intensity mode on the Marc Pro Plus+ I could tell that my legs felt significantly “fresher” the day after training versus without the Marc Pro Plus+.  To actually verify this I did several hard workouts and then used the Marc Pro Plus+ on one leg but not the other. When I woke up the next morning I could tell a difference and the leg on which I used the Marc Pro Plus+ was fresher feeling. I think the big difference using the Marc Pro Plus+ is that you just feel better when you go out for a workout the next day. I just didn’t experience that heavy dead leg feeling that I have felt previously after hard workouts.”
