cable devices

who here has used cable devices, and what were your results with them?

also, what ones did you find useable for the most different exercises?

i’m asking because i don’t have room for a weight bench or rack, but i want to add a little more resistance to the BW exercises i’m doing.

that, and i travel often enough that i want to take the stuff with me.

John Brookfield wrote this book recently. You might want to thumb through it if you can find a copy. That might be hard since it appears to only be sold online. Then again, I haven’t read it and it’s a bit expensive for such a thin little thing. But it does sound like something you could use.
