Lostboy saidi am unable to relate to your problem.
yep. i can't relate either; my butt has it's own zip code. fortunately, it works on my body.
however, to try target your gluts more specifically, try this:
lying on your side, if your legs are aligned with your torso (at 0 degrees from centerline), shift your top leg backward with locked knee and toes parallel to the ground (and facing forward) by about 20 degrees. keep your hips stacked on top of each other.
then lift this shifted leg up, by leading with your ankle as high as you can raise it. that burning sensation in your butt you'll feel should be glut medius/glut minimus. the weight of your leg will initially be enough; as you get stronger, invest in ankle weights. i think you'll enjoy the results. if you don't, well, i tried.
good luck. if doesn't make sense, send an email to me and i'll try to elucidate further.
