Purpose:? These machines are designed to isolate the muscles that spread the legs apart and bring them together.

Pros:? The machines allow you to feel the burn in the targeted areas.

Cons:? Despite the perception (mostly among womem) that these machines “tone” flabby thighs, they don’t actually apply enough resistance to burn many calories.? Because they don’t allow the legs to stabilize a load like squats or lunges, the abductor and adductor don’t build much strength or muscle.? Plus opening and closing your legs in a public gym is just asking for trouble.

Verdict:? Bad.? “If you want strong, athletic looking legs,” says Jason Ferruggia, an MF training advisor, “you need to squat, lunges and deadlift.”? Those simple movements will train the thighs’ inner and outer areas much more efficiently and without comprimising your manhood.

Men’s Fitness March 2008

Amazingly these machines are still in many fitness centers and gyms. It isn’t bad enough that women are still using these contraptions, but amazingly I also see men using these useless machines. Why? outside of shear laziness and ignorance, I haven’t a clue. The adductors and abductors are worked to a much higher degree by performing multi-joint lower leg exercises like the squat and it’s variations.

There is no such thing as a free lunch. Working legs properly, like anything that yields good results, takes effort. If you can talk while you’re performing a set, go home. Start taking your sets to the point at which you start breathing hard and feeling a deep burn in order to get the gains you want

Performing the good morning is an excellent choice for strengthening and building the posterior chain, which includes the lower back, glutes and hamstrings. The glutes (butt) and the hamstrings are responsible for hip extension while the muscles of the lower back (erector spinea) are contracted statically.

Because of the large degree of hip flexion, the gluteus maximus and the hamstrings are utilized throughout the movement. The glutes work in unison with the hamstring to extend the hips in the concentric (raising) part of the movement. The hamstrings, located on the back of the upper thigh, become more involved as you begin to decrease the degree of hip flexion while raising the weight. The erector spinea, which run the length of your spine on both sides, are statically contracted throughout most of the movement, keeping the normal curvature of the spine. A static contraction of the rhomboids and the trapezius muscles help maintain the shoulders.

Extension of the body occurs when the upper body, torso and pelvis rotate up and back. The biggest mistake I see with this movement is allowing the back to ?round? and magnifying the kyphotic (upper back) curvature while de-emphasizing the lordotic (lower back) curvature. I need to add that a slight curve of the upper back will present no danger and will happen to most while using heavy weight, but if you look like a big question mark (?) while performing the exercise, that?s a different story.
