A Lat Bar is a good addition if you are after a more complete home gym.I have one that attaches to my bench and it is very sturdy.They allow you to do lat pulldowns,which is good if either you need to use less than your bodyweight (can't do chin ups/pull ups) or more than your bodyweight (chin ups are too easy) or if you just plain have nowhere to do chin-ups.A lat bar will also allow you to do tricep pressdowns,a very valuable movement in upper arm development.
