What is the best exercise tool, high-tech machines, or free weights?
You can find this information laborious; however, it is necessary to delineate the differences between high-tech equipment and non-high-tech equipment in order to produce maximum fitness in minimum time.
Much of the equipment on the market is practically useless. Just knowing the basics
design principle and function, not only of the human body, but also of the equipment,
Can you decide what is the most efficient way to exercise? With that goal in mind,
offer the following:
Once upon a time, the horse was the fastest means of transportation. If one’s goal
was going from point A to point B, the horse was faster than walking.
Those who did not have much time to lose took a horse, quickly reaching the destination.
Others have walked and finally reached their destination.
Currently, the fastest means of transport is a jet plane.
If one’s goal is to get from the east coast to the west coast, as fast and safe as
possible, the plane is the best option.
The same goes for choosing between exercise equipment that is not high-tech and high-tech equipment.
Non-high-tech is today’s equivalent of the horse. High-tech equipment is today
equivalent of jets. This is not to claim that the proper use of free weights and other
non-high-tech equipment cannot be beneficial; however, for maximum results in
minimum time there is no comparison.
The functions of the human body require the use of an exercise tool design that
it includes certain biomechanical parameters that non-high-tech equipment lacks.
Function dictates design.
One of the main reasons is the stability of the body provided by high-tech equipment. We are all
aware of force-counterforce laws and stresses exerted on the body during
The support provided to the body, while lying down or sitting, during high-tech exercise,
helps stabilize the body, absorb counter force, and allows monitoring and
Maintain the correct body position.
This effective removes unwanted stress on other segments of the body and eliminates
Injury during exercise.
Free weights, when used with multiple benches and seats, can help modify some
the problems associated with counterforce. However, not as well as
There are also many other bodily requirements for productive exercise, which only
Properly designed high-tech equipment can provide
The bars were a huge leap forward, because they allowed for the basic requirement
of productive exercise: Resistance, which is applied to a contracting muscle, with
greater effectiveness than previously existing tools.
In truth, it doesn’t matter to a muscle whether you’re lifting a 50-pound bag of sugar or a
50 pound bar. The main difference is the comfort factor.
Performing a barbell exercise is easier. One of the main reasons is that it can be gripped better
than a sack of sugar. For the muscles that do the work, it’s still 50 pounds. the
The amount of resistance used determines the amount of muscle fibers contracted.
Just as weights were a quantum leap, so is high-tech equipment compared to
bars. Resistance application (the basic principle of progressive exercise and
proactive physical therapy) improves a contracting muscle.
However, not all high-tech equipment incorporates all the requirements of
maximum progress. Some of the requirements to consider are:
Positive and negative resistance
A properly designed exercise tool MUST provide two aspects of resistance.
Resistance is provided when raised and resistance should be provided when the
Sometimes called concentric or positive resistance, this aspect occurs when one
is to contract or shorten a muscle. Lowering resistance or eccentric, negative
movement and occurs when one relaxes or allows the muscle to lengthen.
Along with positive and negative resistance potentials, the ability to stretch and
Pre-stretching a muscle is essential with an exercise tool.
Pre-stretch and stretch
Stretching is pushing or pulling a part of the body into a position that temporarily exceeds
the existing “normal” range of motion. It is related to the angels of the joints, muscles,
and connective tissue.
Pre-stretching occurs when a muscle is moved to a position of increased tension.
just before the start of a positive contraction. Pre-stretching has two effects that
result in greater benefits:
(1) The muscle is elastic, like a rubber band, and stretching it slightly, just
before movement, it actually produces elastic energy that can be used in the
contraction and help you use more resistance.
(2) Pre-stretch fires a nervous system stretch reflex that requires
muscle fibers, to use in the next movement
Now, we have set four requirements for a complete range, maximum productivity.
1. Positive work: Building resistance.
2. Negative work: Lower the resistance.
3. Stretch: A slight lengthening of a group of muscles.
4. Pre-stretch: Takes place in a slightly extreme range just before stretching.
It must be done carefully and with the minimum speed.
5. Balanced resistance and variable resistance
As muscles contract and move through a range of motion, they do so with different
degrees of motion and force potentials.
This is a natural consequence of muscle contraction and human movement.
You know that it is possible to handle more resistance in some exercises than
others. You may not realize that when exercising, your muscles
involved, the force levels are also changing as they move.
That is one of the reasons why some positions of a movement feel easier than others,
although the weight remains constant.
Because muscles have a variable force potential as they move, it logically follows
that, the resistance must vary according to the actual potential of muscular force.
This is called automatically variable resistance when incorporated into a high-tech system.
machine design. When referring to different muscle groups and variable strength
potentials, is called balanced resistance.
High-tech equipment must provide automatically variable and balanced resistance.
resistance. The resistance should vary automatically and according to the force
potential, as one moves through a range of motion. With weights, resistance
does not vary.
Now we have established, two more requirements for a superior exercise tool,
neither of which provides bars:
6. Balanced resistance: resistance that is neither too light nor too heavy.
7. Automatically variable resistance: resistance varies within the range of
movement and according to the strength potential of a particular muscle group.
8. Unrestricted speed of movement
Although it should be possible to perform exercise movements at various speeds to
high intensity contractions, throwing in resistance is not beneficial. But nevertheless,
Unrestricted movement speed is a requirement. The weights satisfy this requirement
just like high-tech equipment.
For best results, do the movements fairly slowly. As an example: the positive
part of the movement should take about 4 seconds, the negative part about 4
seconds (as a safe example).
By controlling the movement, the muscle always contracts. A fast speed of
movement towards is potentially dangerous.
Aggravates force. First for the sudden and abrupt beginning. Moreover, as the
the resistance hits a part of the body, at its final destination point.
If a muscle is not prepared for the initial sudden jerk, there is the possibility of injury.
9. Resistance in the fully contracted position
Unless there is resistance in the full muscle contraction position, it is impossible

tools, like weights, don’t. Therefore, it would indicate that the resistance is not
supplied full range, only partial range. This reduces the potential for exercise.
For example, in the two-arm curling movement with a barbell, there is no
resistance supplied to your biceps muscle in the fully contracted position.
With properly designed high-tech equipment, there is resistance in this position.
We already understand that resistance, properly supplied, is the key to maximum
results in exercise.
10. Direct resistance
When possible, resistance should exist directly in the muscle under contraction to
ensure the best results. Two similar exercises that we can compare are the chin with two arms.
movement and a high-tech pullover machine.
11. Full range resistor
Muscle contraction provides the movement of one or more body segments. These
Segments have what can be called a full or full range possibility.
Ideally, one should be able to exercise one segment of the body through a full range of
movement. Of course, an injury can prevent this from happening; however, the goal
it’s too much to improve full-range movement.
This rotary motion requirement is the most difficult to visualize. In simple terms,
is: Resistance that moves on a common axis with a segment of the body moved by
An excellent invention in the history of exercise is a device called a cam. Is a
camera that allows experienced users maximum productive exercise.
In simple terms, the function of a cam is as follows:
A cam redirects resistance, so it travels on the same force curve as the one exercised.
body segment. The resistance is redirected to travel in a twisting motion and in the
same force curve of the moving body segment. At the same time resistance
it is directly OPPOSITE to the intended move.
This ensures resistance, normally provided by a stack of weights. The lifting of the
The weight stack is made through cables or chains that are attached to it.
Cables or chains are connected to the cam system and, as the cam rotates, the cables or
chains wrap around cam. The radius of the cam that the chain is wound on varies.
The distance from the center mark of the cam radius, to the point where the chain
Play while wrapping determines variation (and assumed balanced resistance).
The point of contact of the chain is directly opposite the direction of the muscle.
Weights and some other forms of exercise equipment do not provide resistance in
in this way. They provide resistance in a straight line, always straight down.
towards the ground, always depending on gravity.
Effective resistance is when you move the bar vertically, directly opposite
the force of gravity.
A cam changes straight line resistance (gravity) into rotational resistance. Is
allows resistance to travel in a curve always away from its
Because weights and some exercise machines can meet only some of the
requirements we have listed, it follows that high technology has the potential to improve
one’s fitness results.
The QUALITY of the resistance is the final determining factor, determining what
