What’s the difference between Marc Pro and Marc Pro Plus?

The standard Marc Pro features one, easy-to-use setting that’s focused on improving muscle recovery and conditioning. The Marc Pro Plus features this exact same recovery setting on the “low frequency” option but also has a “high frequency” setting for immediate pain relief beyond muscle soreness. If you’re looking to improve recovery, muscle conditioning and prevent overuse injuries, the Marc Pro will accomplish these goals. If you have pain in joints or problem spots like the low back and neck, the Marc Pro Plus high frequency setting will provide on-demand pain relief to those areas.

What is the difference between Marc Pro and a TENS unit?

TENS is an acronym for Transcutaneous Electrical Nerve Stimulation. TENS are inexpensive medical devices that attempt to mask pain symptoms by interfering with nerve signals; they have no rehabilitative, recovery or conditioning benefits whatsoever. Marc Pro activates a cascading series of physiological effects through a specific type of muscle contraction that lead to enhanced recovery and conditioning.

How long should I use Marc Pro for?

For the regular Marc Pro (or low frequency setting on the Marc Pro Plus), you can use the unit for as long as needed to ensure you’re feeling recovered – an average session length is 30-60 minutes. Longer sessions will provide more benefit as the more nutrients and waste are exchanged, the better recovered your body will be. Keep in mind the contractions created from the device will never cause fatigue so you’ll never “overdo it” or experience diminished returns from using the device for hours at a time. You can also split up hours between the day to fit your schedule.

The Marc Pro Plus high frequency setting can be used for 30-60 minutes at a time. 60 minutes of high frequency used correctly should shut down pain for 1-4 hours after the session. To avoid skin irritation, we recommend taking a break after 60 minutes, but you can use high frequency again later in the same day.

When do I use Marc Pro?

There is no bad time; before, after or in between activities are all beneficial. Using Marc Pro after strenuous activity will speed the recovery process and make you feel better after just your first session. Using Marc Pro before activity will help loosen and warm up muscles. And using Marc Pro regularly will improve the conditioning of your muscles allowing them to last longer and perform better.

Do I need to follow the exact pad placements in the manual?

Not exactly. The pad placements in the manual and our online guide provide great starting points, but we encourage you to move the pads around to where it works for your specific body. You don’t need to be an anatomy expert, rather you’re looking to get a contraction in the muscle area you are sore or trying to recover. For example, if your lateral quad is what is overworked, follow the quad placement in the manual but arrange the pads so that the lateral part of the quad is contracting. If you’d like to go over pad placements, reach out to us by clicking here.

It might take a handful of pad placement adjustments to get the contraction going well but that’s okay, once it is contracting well you won’t need to touch it at all. Of course, follow our contraindications by never putting the electrodes across or through the chest, on your throat, or head.

Where do I place the electrodes?

The instruction booklet and our online guide outlines many common and popular electrode placements and should be reviewed carefully before beginning use of your Marc Pro. But remember your specific training goals and your body’s response will be a key factor in determining the ideal electrode placement. If you’d like to speak with someone about electrode placement, please click here to schedule a call.

What body position should I be in during Marc Pro sessions?

You should be comfortable and relaxed during sessions, especially the part of the body you’re using the unit with. Your body position should allow the Marc Pro to comfortably contract and relax your muscles with as little resistance as possible. Click here to see some body positioning examples.

I’d like to go over pad placements, do you help with that?

We provide concierge service to all customers or prospective customers to help with pad placements or answer any other questions about the device – whenever it’s convenient for you. Please call at 855-627-2776, send an email to, or schedule a call by clicking here.


Why is it so valuable to recover faster?

When you recover faster, you’ll be more comfortable, you can get back to training or playing sooner and you can train harder.  Recovering more fully before going back to activity also means that you will perform better and you’re much less likely to get injured.

Why would I want better conditioned muscles?

Conditioned muscles can do more “work”, last longer, recover faster, and perform better. Using Marc Pro regularly can help condition your muscles so that it takes longer for them to break down. By increasing the overall throughput of nourishment and waste to and from the muscle, the muscle has an increased capacity to do more work – its conditioning has improved and it performs better.

Can Marc Pro build abs or other muscles?

No. We have been in this industry for 30 years and despite many claims of muscle building from many companies we’re yet to see any real life proof. We’d all love to get abs of steel while sitting on the couch, but we’re of the philosophy that when things sounds to good to be true they usually are. For strength and muscle building we do not believe there is a substitute for hard work … With that said the ability to recover faster is very real and can be demonstrated immediately using Marc Pro on someone with fatigue or soreness. If you recover faster workouts can occur more often and be easier, which in turn can improve your training outcomes. And when used regularly Marc Pro will improve the conditioning of your muscles to enhance future performance.
