I had a Idea...... if I wear Arm and leg weights for everything I do, and I mean EVERYTHING...... from work, to walking around the house, and for my primary use...... Parkour Training. Maybe I might get better results and build muscle ALOT Faster. I desperately upper body strength, my legs are strong but could be Improved also. So I looked online for something that I can wear, but won't get in the way or be too big, anything I do without them, I'll need to be able to do with them also. some just looked to bulky, and I just didn't like them. but I found two types of weights that I think that can go good with Parkour Training. the other three I don't know, I just linked them for the heck of it. and for your feedback on this topic.

Tell me what you guys think, I am definitely thinking about getting them, but not in one paycheck cause they are kinda expensive.....

and these I'm not to sure if they would be good for Parkour, but if its crappy out and you just want to work on conditioning they seem good.

I've thought about this before, and it seems like a flawless idea.

But the only real problem about it is the major stress it places on joints. Your ankles will hurt and your knees will beg for mercy, eventually.

And if you run with improper form on cement...

My Running form is pretty good..... and it wouldn't be like a cannon ball strapped to my arms and legs, I think they are just two pounds.

This is my opinion, not based on anything other than my thoughts and experience (which of course are heavily influenced by these forums).  So take it for what it's worth.  But I don't think you're going to help yourself out too much, and possibly be counter-productive. 

When your body puts on more weight think about where that goes.  It is mostly in your torso and lessens the farther out you go.  So your body will never have an extra 2 lbs on each wrist and ankle unless you are wearing weights, or you become extremely obese.  In other words, you are in no way mimicking a natural body type that you plan to have.  Because of that the muscles that develop in response to the weight are going to develop to move a 2+lb hand, which probably won't translate well to helping your natural body move naturally. 

Now for the risks I can see, which again are not based on scientific findings or even anecdotal ones.  Just like with a lever, weight that is farther out requires more force/strength to control.  Hold a barbell in at your chest then hold it out at arms length.  The latter is much harder.  So even though 2lbs. may not seem like much it may be equivalent to much more, which may put far more stress on your joints than you realize.  Also, if you don't compensate well for that weight with your balance then you might hurt yourself doing a vault or something.  If you do compensate well then you run the risk of compromising your balance without the weights.  Neither of those seem positive to me.

Now, if you really want to invest in something like this right now, a weight vest I think does have many good uses.  Just not as something you wear during ALL activities.  I have never used one so am not the best person to tell you how great or horrible they are.

This has been discussed several times in many threads involving "weight vests".  Do a search.

In short, your body adjusts how its muscles are used with the amount of weight at is on the body.  When you remove the weight the use of the muscles is altered to compensate for the weight and everything is out of whack, in most cases.

The way I see it, the points of leverage and the center a gravity will all kinds of crazy. I really don't see it as all that beneficial.

Though, I've always thought you could get some sort of weighted full-body suit that proportionately placed the exact same amount of weight on every square inch of your body might work. Then you have to worry about mobility. Plus it would be hot. And really dumb looking. All in all, a not good idea.

They pretty much have this. Not over every inch of your body, but loading more than 80% of it. It's called a barbell and high-bar position! 

wait, so if i trained in a room with 10x gravity, it wouldn't be a good idea?

Hmmm... With gravity, I'd say the problem would be our organs wouldn't adapt to the weight after a certain point. I'd think any increased gravity would increase risk for all sorts of organ failure, especially the heart if you're doing anything strenuous. My small 2¢.

Eh... there's a valid point somewhere in there, but that example is not quite correct. Adaptations would manifest after a while, assuming we somehow survived the conditions to reproduce through hundreds of generations (which definitely could NOT happen with the gravity of Jupiter, but I understand that was just an example). And the astronauts getting weaker isn't the same type of adaptation. Back before they knew that exercise could counteract the atrophying effects of zero gravity, astronauts who had spent relatively long periods in space didn't experience slight decreases in musculature and bone mass, it was severe and acute. In zero gravity, neither your muscles nor your bones have to bear even the slightest load, so your body just stops putting energy into maintaining them. That's something already programmed into human beings, whereas adapting over hundreds or more generations requires a change in genetic makeup.

Exercise in increased gravity would be okay, so long as it were only exercise. The body is only made to handle a small range of conditions. If you were to live your whole life in increased gravity or unnaturally added weight, your bones and muscles would adapt to a point, but in the end would not be able to cope. (In the case of increased gravity, your organs would also be placed under increased stress, and they can't really adapt at all.)
