Sure it is push and pull, but it is mostly push...

It does that but, it is used traditionally because eventually one leg compensates for the other when doing a squat. So if weight lifters aren't careful they'll end up with one leg larger than the other... for cycling purposes the benefits also include the strengthening of all the stabilizing muscles.. which is why i would say "no machines" since we want dynamic strength not size.
