Hello folks,

I've read several articles lately and I've seen several mentions of closed-chain and open-chain exercises. Can someone explain what this means, perhaps with examples. Further, why is it an important distinction?

Thank you...

Open kinetic chain = end of the body segment is not attached to ground (e.g., leg extension). Artificial, not something your body encounters naturally.

Closed kinetic chain = end of body segment is anchored (e.g., squats). Natural function of the body.

It's not quiet that simple. Throwing a ball, kicking, the overhead press are all open chain movements. I wouldn't consider those movements unnatural. The following links give some background and clarification. All w/f safe.

Don't get overly concerned about the difference.

Once you do know the difference, you may try to do both types of exercises for the upper and lower body. IMO, the lower body tends towards closed chain (as we deal with the ground with our legs) and the upper body tends towards open chain (to put things over our head).

This difference can become quite muddled. I suggest you get a feel for the concept and utilize it as best you can, while not becoming overly concerned about it.

I agree with garrett - never once have i considered that classification when programming for someone. if you're unsure about whether or not a particular movement is appropriate or beneficial in a given situation, that isn't going to help.
