Strength & Flexibility

By August 6, 2013 Benefits No Comments


The degree to which someone can increase his or her strength when following a proper strength training workout program varies from individual to individual, and depends on the training program. On average, after approximately six months of starting a strength training program, people can expect to see their strength increase by about 25–30%. If exercising by NET's training principles, and especially under the supervision of one of our fitness clinicians, higher rates of strength increase can and should be expected.



There are a number of studies showing how flexibility can be improved by proper strength training alone (1, 2). In 1975, one particular study was conducted with the United States Military Academy in West Point, where the participants trained with High Intensity Training principles using Nautilus exercise machines (the forefather to MedX) (3). The subjects increased their flexibility on an average of more than 10% for three different evaluated items.

In a healthy trainee, such improvements in flexibility (from strength training alone) are possible due to these key factors:

  1. Training isolated rotary movement muscles to their full Range of Motion (ROM).
  2. Applying the right amount of tension at the muscle’s fully extended position.
  3. Using equipment that is designed and can be adjusted according to individual’s body type where the two dimensional movements are performed in accordance to muscle and joint function, in order to avoid acute or long-term chronic injuries.

Increased strength and flexibility can help slow the aging process by preventing disease and allowing your body to better react to situations such as falls. It can also make your daily life much more enjoyable, allowing you to take part in activities like playing with your kids or grandchildren without getting winded or having to stop due to physical limitations.


NET only uses equipment that is unparallelled in strength and flexibility gains with near-zero chance of injury.
