Lifeline TNT Cable System

I have used cable systems for several years to add variety to my workouts, I usually pick them up at my local Target, or Walmart, but these are cheaply made, and don't hold up. I had read reviews on the Lifeline system on Amazon, and other website, so I decided to give it at a try. What I like about the system:

1) Very durable and well made, which is good since this is not a cheap system
2) You can do a variety of exercises with it, in a small space
3) The door anchor offers the option for additional exercise
4) The three cables offer a tremendous amount of resistance

What I did not like

1) There should be an available instruction manual, or booklet besides directing the buyer to a website.

2) Even with only a single cable, this has a kick, you need to have stretched and warmed up first, to avoid pulling or straining a muscle.

If you like to work out with a cable system, this is a very good setup
