Your wrists are bent back with your thumbs not around the bar. Get your thumbs around the bar and straighten your wrists so that your middle knuckle is up. Elbows could be a bit more in towards your body in the setup (tight armpits). Squeeze your abs and quads tighter before each rep.Be careful not to let the bar drop and your upper back round down when you do the hip reach. Finish each rep by pushing your chest through a bit to get the bar over your shoulders. Make sure you read this: The First Three Questions | Mark Rippetoe since you are failing reps.
