I can see the common error that Nodeal might be making. People think of these machines as only for the glutes and inner/outer thighs. Which tend to be a womens thing. And, as said, these exercises can affect the muscles in a whole different way.
Don't be fooled by the term Abduction (out & away) & Adduction (in & close) machine. They are not restrictive to "girly" movements. And not restrictive to machine protocol only. Can be very effective and have a place in any serious BB'ers training. From overhhead pressing, extensions (side, front & rear raises with influence on the supraspinatus), flys, stepup's, lunges, inner/outer thigh work, special designed glute/maximus units, etc. Included are pulldowns/pullovers. Cable training is also suited for most of the above movements.these workouts
Art Jones designs were to take in account the importance of Ab/Ad work. Rehab workouts depend on these type machines quite a bit.
Lunges are a very effective way to train the quads/hams/glutes. With the walking version, beginners may find keeping their balance after so many reps/distance a challenge. Start light, if not use to this movement , at first. Might also try lunges with the front/leading foot on a exercise box of 12 to 16 inches. Which will offer a better stretch to the hams/glutes, including the quads themselves. Good Luck.
