Stretch To lag

Ive been messing around with a rig, just for fun. On it I have a lot of bones that are stretching to empties which are parented to other bones, so the stretching bones can act like muscles. Anyways, I tried a little walkcycle, and I noticed that the musclebones are lagging.

Is there a way to fix this? Does my question make any sense?

If it doesnt, I can upload a file to show what I mean…

Thanks.
