the difference in strength you mentioned usually occurs as a result of the difference in training methods. someone who lifts weights alone will be bigger than a guy who wrestles, does BJJ or Judo- but the guy that does the grappling will have what appears to be more strength because his muscles (and support muscles) are more developed and trained to respond to the dynamics of a moving weight such as a person.
weight lifting will work support muscles, but not to the extent that grappling will. you also tend to have better balance and stability with grappling training than you do with weight training alone.
if you want some workouts that will help you get the grappler strength without the grappling you'll need a friend and a Gi. if you can get those, post here again and i'll tell you about some of the workouts.
