Does anyone know how to set a routine like this up? Can I have the chain set in three positions which mark the start, mid and end of a deadlift (for example) and then pull against each of these points for 5 seconds? Would I need to do multiple reps of this?
I often will work one link at a time throughout a specific range of motion. This is what I did when working extensively on one arm overhead presses. I would start at the bottom and train each link for one or two max efforts. One day I would start at the bottom, and the next session I would start at the top (to have days where I hit each region fresh).
You may not need to hit so many angles of course. It depends on available time, what else you are doing, etc.
Lastly, I recommend the addition of a strong spring link if possible. It will add a dynamic element to the isometric work. I've found the addition very useful.
