Heya, hmm if I'm not mistaken, the co ordination of the dumbells is a neuromuscular communication situation, so that should improve with continued efforts. I have that a little bit with the decline, because I just started doing them. I actually pick one day for reg, one for incline & one for decline, just to make sure ALL of the muscle is in use in the week

The same for shoulders, front raise, lateral, reg press. Less boredom too.
Not sure if the db would be as viable for hip thrusts never tried them, not sure the weight would be evenly distributed if the fullcrum of the lift is off center ? If there are no BB in the ladies section move to the mens, your lifting is just as important as theirs. Yes the hip thrust does have effects on the frontal hip area, perhaps some ab, in a isometric way. However the main muscle is the glut. Make sure you push all the way up & squeeze. Oh & make sure your hamstrings & gluts are warmed up & stretched before doing these, if they are normally tight.
Myself I had to take today off due to uterine cramps from hell waking me in the middle of last night. At 47 one would hope the discontinuation of that body function would leave gracefully, but no. Picked up business papers, trademarked business name, working on website, lots to do on a day off ? People are asking for card which is made but not printed yet, next order of business eh. Will get on that now..good luck lynne
