Safer than what?
Who claims this?
Why don't you ask the people claiming that for the theory?

Isometrics is basically anytime you apply a muscular force against resistance without any movement of the associated joint(s).

I know about the claims you are speaking of. I think people are expecting that you would go and research as much alternative info as you can and come back with specific questions.

How do you apply a muscular force without any joint movement? I'm gonna have to look into this, sounds interesting

[EricT]

LOL, push against an immovable object and you are applying a muscular force but the nothing moves. The muscle contracts but it's length remains constant. I should probably say "appying muscular effort" without any joint movement to be more clear.

The biggest benefit right off the bat is rehabilitation.

OH! lol, I was thinking you push against a wall...but then you would be pushing yourself back from the wall. Basically I pictured closed kinetic chain exercises. My bad...

eric is right: i use it as one of my 12 rehab exercises.

to the OP: did u come across this on the t-nation site???

[EricT]

Oh, yeah, Kane, lol, I see what you're saying. It's assuming you are not able to overcome the resistance of your bodyweight because of the exercise involved or because your body is anchored in some way.

Hi guys,

I'll be more specific.

Isometric exercises are supposed to be more safer than the usual weight lifting exercises.

They are also more productive becuz. -

1.They avoid any intramuscular friction.

2. reduce any momentum factor.

3. Don't have any negative phase where intramuscular friction is supposed to help in lowering the load.

4. They require considerably less motor skill than weight training exercises and hence muscle retention rate is increased.
5. They are similiar to closed chain kinectic exercises & thus muscle retention & strength rate is increased.


Are these claims true.

If you wanna get stronger at pushing walls, then yes. But when you limit your range of motion like this, you will only increase your strength in that perticular position. It just doesnt seem like a logical way to train to me.

It may be safer, but if saftey is really your concern, then start out with machines, then move to free wieghts once your more comfortable.

perfect example: Wall sits, just lean on the wall with your back facing it, and act like you're sitting in an invisible chair.
