Why MedX® Equipment?

Why MedX® Equipment for the 2020 Method?

The 2020 workout is a safe, research-based, slow and controlled exercise program that suits all fitness levels. What’s important  is not how much weight you lift, but the way you lift it. It is important to be familiar with the concepts and terms below to understand what makes MedX® superior to other exercise machines on the market and why Studio 2020 Fitness chose to use them exclusively. Incorporated into every MedX product are decades of experience and millions of dollars of independent, university-based research. MedX is the most technologically advanced fitness, sports and medical/rehabilitation equipment available.


Arthur Jones, the inventor of Nautilus exercise equipment in the 1970s, developed MedX® exercise equipment in the 1990s. Jones funded a research project to develop a superior machine that could measure lower back strength and be used to treat lower back pain. After millions of dollars of research, Jones sold Nautilus, and the MedX® Lumbar Extension was created. At the same time, a medical machine called the MedX® Cervical Extension was designed to treat neck problems. After years of research, it was discovered that MedX® had the highest success rate for lumbar (back) and cervical (neck) patients (94%). The results from his machines were so successful that Jones went on to develop a complete line of MedX® exercise equipment.


MedX® equipment is set apart from other strength training equipment by the following facts: they have low friction, small weight increments, short weight strokes and proper strength curves. What does this mean to you?

Why low friction is important:

The amount of friction plays a vital role in the process of improving your strength and changing the shape of your body. MedX® has between 0 and 5% friction while traditional equipment has up to 30%. For example, if you had 100 pounds set on a machine with 2% friction, you would be pushing 102 pounds during the positive phase of the movement and resisting 98 pounds during the negative phase. This is a four-pound difference between the positive and negative phases. On traditional equipment, with up to 30% friction, that 100 pounds turns into you having to push 130 pounds during the positive phase and resisting 70 pounds during the negative phase.

That’s a difference of 60 pounds. With that degree of difference, your muscles have ample opportunity to recover during the negative phase, meaning that you will be unable to effectively fatigue the muscles, and, more importantly, will not get the most benefit from your workout.

Why small weight increments are important:

MedX® allows you to increase or decrease the weight being used by 2 pounds, whereas traditional equipment typically allows five-to-ten pound increments.

Why this is important is based on two fundamental premises:

  1. It is critical to fatigue the muscles within one-to-three minutes or four-to-eight repetitions.
  2. As a person gets stronger, the weights need to be increased to work the muscles more deeply each time.

This is where the problem of large weight increments comes in. If you increase the weight too much, the muscle may fatigue sooner than the required one minute or four repetitions. Conversely, if you don’t add enough weight you may perform too many repetitions and be on the machine longer than the three-minute, optimum time frame. This is why the small weight increment of two pounds that MedX® features is the most beneficial to effectively work your muscles.

Why short weight strokes are important:

MedX® is the only equipment company with a short, one-foot weight stroke. Most companies’ weight stroke is two or more feet. What that means is that the weight stack movement of only one foot on a full-range repetition is safer and smoother than a longer weight stroke. Another reason the shorter weight stroke is important is that if you have 120 pounds on the one-foot weight stroke machine, then that means you are moving 120 pounds. On the other hand, if you have 120 pounds on a two-foot weight stroke machine, then you are really lifting about 240 pounds depending on the machine. That also means that if you increase the weight by two pounds on a one-foot machine, you really are increasing it by two pounds, whereas on a two-foot machine you are raising it by five pounds, which equates to a 10-pound increase.

Why proper strength curves are important:

Strength training equipment needs to support the strength curves in the body. Most equipment is incorrect in this regard. Each muscle has a different natural strength curve, so each piece of equipment  needs to be properly calibrated and designed to accommodate the specific muscle group it is targeting. MedX® accomplishes this by the usage of cams/levers to provide variable resistance.

MedX® is simply the best, most effective strength training equipment on the market.


Cam – the rotating piece in the equipment by which rotary motion is transformed into linear motion or vice versa
Friction – the force that resists motion between objects in contact
Negative phase – the part of the exercise where you are lowering the weight stack back to the starting position, in this phase your muscles are stronger
Positive phase – the part of the exercise where you are raising the weight stack to full extension
Strength curve – the natural variation in strength you possess throughout full range of motion of any single exercise
Weight stroke – the distance the weights have to travel to full extension
