What is Manduu?

Manduu is an electrical muscle stimulation (EMS) workout that will revolutionize the way you think about building and sustaining muscle. Until now the only way to build muscle has been to lift, hold, push or pull something heavy, which carries inherent risk to joints, tendons and ligaments.

Manduu changes that by using electricity instead of weight to create the resistance during a workout. This makes possible a workout that is both ultra-low impact and incredibly effective. Because no heavy weights are involved, the risk of injury is significantly reduced.

Moreover, because the electrical pulse penetrates deep into muscle fiber during the workout, an EMS session is extremely efficient. Nearly 100 percent of muscle fiber in nine major muscle groups is activated during a workout, yielding the results of 6-8 hours of traditional strength training in just one 15 minute session.

Each workout is led by a personal trainer who is specially trained in EMS technology and who tailors the program to each client’s individual fitness goals. Trainers work with no more than two clients at a time. Nearly every adult can participate, from professional athlete to senior citizen.

At each workout session clients also receive a full body scan using InBody™ technology to measure muscle mass, body fat, visceral fat, hydration, metabolic rate, and other key metrics with clinical accuracy. This allows clients to quantify and measure their fitness results.

Is it safe?

Absolutely. Manduu machines run off of a low voltage battery. There is not enough electricity in the machine to hurt you, and nothing is plugged in to a wall.

EMS technology has been used in medical settings in the U.S. for years, and you may have experienced a form of it if you have received e-stim as part of a physical therapy treatment. The same technology is now being used to help paraplegics walk again. [1] Our ownership group includes orthopedic surgeons who have experienced Manduu for themselves and found it to be safe and effective.

Russians and Europeans have been using EMS to train elite athletes since the 1970s, and the technology gained widespread acceptance among the general public in Europe about a decade ago. Today there are more than 1,700 EMS studios in Germany and Austria alone, and more than 50 million EMS sessions were logged in Europe in 2017. The U.S. Food and Drug Administration recently cleared our technology for use in non-medical exercise settings, paving the way for Manduu.

Electricity aside, Manduu is one of the safest strength-building options available. CrossFit has injury rates that range from 20-75%. [2, 3] Because we do not use heavy weights and because each session is led by a certified personal trainer, Manduu is an extremely safe fitness solution.

15 Minutes? Really? It sounds too good to be true.

An EMS workout activates more muscle fiber than you can activate on your own. When you rely on your brain to send an impulse to a muscle, at most you are using between 60 and 65 percent of your muscle fiber. The external pulse from our EMS machine penetrates deep into muscle tissue, activating nearly 100 percent of the fiber. Quite simply, Manduu does more for you than you can do for yourself.

Our workout is also a whole-body workout. We activate muscles in nine major muscle groups at once, so there are no more arms days, legs days, or core days. One 15-minute workout covers it all.

How do I know that it works?

We firmly believe in tracking your fitness progress. An important part of each Manduu session is a full-body scan using InBody™ technology to measure skeletal muscle mass, total body fat, visceral fat, metabolic rate, and other key body composition metrics with clinical accuracy. There’s no guessing with Manduu.

In addition, many of our clients have told us that the proof is in their sore muscles!

How often should I work out with Manduu?

Most of our clients begin by working out once a week but eventually migrate to working out every four or five days. You can work out as frequently as twice a week with Manduu.

Who can Manduu?

Most adults. Our clients range from professional athletes to senior citizens, from overweight desk jockeys to stay-at-home moms, and include everyone in between. Except for those with a few medical conditions, just about everyone can Manduu.

I have bad knees (shoulders, elbows, etc.). Can I still do Manduu?

Electrical stimulation has been used for years in orthopedic rehab settings, so it’s likely that Manduu is perfect for you! Not only can your certified personal trainer design a workout that accommodates any chronic joint conditions, but a Manduu workout is super low-impact. Plus, building muscles around joints has been proven to help relieve pain, restore function and range of motion, and help avoid further deterioration and surgeries.

I have screws (or pins or plates) in my elbow (or knee or ankle). Can I participate in Manduu?

Probably. In general, metallic implants are not a problem as long as an electrode will not be placed on top of them. We are able to work around most implanted metal as long as we know about it in advance. Please call or email us to discuss your situation.

Is there anyone who can’t Manduu?

There are a few health conditions that prohibit participation in Manduu. We’re sorry, but we absolutely cannot make an exception if you have any of the following:

  • Cardiac stent
  • Severe heart disease
  • Severe COPD or emphysema
  • Pacemaker
  • Blood clots
  • Any other implanted electronic device such as a bladder stimulator, defibrillator, etc.
  • A seizure disorder, such as epilepsy
  • Cancer, even if it is in remission.
  • If you had breast cancer and a mastectomy, you may be able to participate but we will need a note from your doctor.
  • You may be able to participate if you have had basal or squamous cell carcinoma in an area where there are no electrodes, e.g. on an ear.
  • Skin infections or disorders such as eczema and psoriasis if you have skin lesions in areas covered by electrodes
  • Kidney disease
  • Pregnancy or breast feeding

There may be other medical conditions that prohibit you from participating in Manduu. Please call or email us if you have questions.

I’m not interested in gaining muscle or looking like a jock. I just want to be fit.

Everyone needs muscle. Having an appropriate fat/muscle ratio is the definition of being fit. Retaining and building muscle has been shown to:

  • Prevent falls by improving strength, balance and flexibility
  • Manage chronic conditions such as diabetes and arthritis
  • Reduce back and joint pain
  • Boost metabolic rate to help stave off obesity
  • Develop strong bones to reduce the risk of osteoporosis
  • Reduce depression
  • Boost self-confidence and self esteem

You won’t look like a body builder if you don’t want to. You will tone muscles and look and feel great!

What is a Manduu workout session like?

Your first session is a comprehensive introduction to Manduu. Allow 90 minutes, although it might not take quite that long.

You will be greeted by a certified personal trainer who will review your health history and consent forms with you. You will then be asked to change into our workout shorts and t-shirt which fit under the electrical suit and are specially designed to conduct electricity. Most people work out barefoot although you are welcome to wear athletic shoes if you prefer. You will complete an InBody scan which measures a number of biometrics and then your trainer will fit you into the EMS suit. Once your correct size has been determined, the electrodes on the EMS suit will be wetted down and you will be connected to the machine. Your trainer will introduce you to the feel of the electrical pulses and lead you through an abbreviated workout.

For subsequent sessions we ask you to arrive 15 minutes before your scheduled workout time so you can change into the workout garments, run your InBody scan, and be ready for the trainer five minutes before your scheduled time. Most clients are in and out of the studio in 30-40 minutes each session.
