There is absolutely NO fitness machine that can work abductor muscles in this manner by pulling you away from the midline of your body at the same time your adductor muscles perform the opposite direction all while creating flexibility and building strength.
The abductor & adductor fly is an exercise performed in a certain manner as shown in this video for strengthening the inner and outer leg muscles. Having a weak abductor and adductors are the single most common issue as we get older starting at the age of 40 and above.
Start with 2-3 sets of 10 repetitions, make sure your form is correct then start building up to several sets of 100 repetitions. As you get better and stronger you can add ankle weights starting at 2 PDS and drop the number of sets to build back up to 100.
Once you reach 100 reps again add a few more PDS to your ankles and start the process all over again.
