Every time that I perform a single leg movement on my right side my right adductor magnus kicks in when the glutes should be firing. I can still feel the glutes working but the adductor contracts very hard. It is often sore after workouts and generally feels tight and over-worked all of the time.
I have tried one leg curl (same str), one leg press (right leg weaker), single leg rdl (right leg weaker). For nearly a year I have cycled through all of the exercises trying for ages to bring up the weak leg. I have only been doing sets on the weak leg and it seems as though whenever I do this my quads or hams on the right side get better but my right glute remains unused. I also notice that the right side is a lot less stable than the left when standing. I should note that I had some dramas with a hypertonic ql on the left side, so I am not sure whether the left glute contracts harder because the back is tight, causing the imbalance.
Do you guys have any ideas for exercises that may recruit the glute without using the adductor at all? I have tried the glute bridge, single leg glute bridge, donkey kicks, side lying clams and lots of low load isometric stuff. I do feel the glute working but as soon as load is added or fatigue sets in, the adductor begins to dominate again on that side.
