You could compare it to an arthritic sufferer wearing splints. Initially helps but the more you rely on splints, the weaker the muscles become leaving you weaker. Only way to overcome it is to dismiss the splints, harder initially, but with time muscles strengthen, hence no need for splints.
Same applies with this apparatus. Good technically on paper, but in the real world, useless, serves no long term purpose. If you had to rely on this apparatus to work, it would be time to call it a day in this career and look elsewhere.
I Don't Think so.
The Problem is Not that you (Need more Muscles or Not.)
The Problem is that Human Resistance has a Limit not only on how much Weight to Carry,
But for How Long, what type of Load it is, at What Height and what Conditions, Etc.
Let's not Forget that Someone who Practices Physical Exercises does not Mean that they Can do a Better Job.
Than a Construction Man because the Physical Activity or Activities Carried Out are Not the Same.
Remember that More Force and Muscles does Not Mean More Resistance.
And Furthermore, in the Event that these Workers Could Actually do Physical Exercises.
Would they have the Time and the Necessary Strength after a Tiring Day at Work.
To do Even More Stressful and Heavy Exercise for just a Few Muscles?
I Don't Believe it.
In Addition, these Exoskeleton do not Replace Human Muscles or Strength.
They Help and Complement each other (Against Accidents) at work.
(Caused by Excess Weight or very Dangerous Activities in general)
for Workers in Certain Things.
Such as Exhausting and Very Uncomfortable Positions for the Human Body that Would Harm them in the (Long Term.)
