Try these 2 variations on side laterals:
1. Side-Lateral Dbell Raises: Bring the dbells ALL THE UP, AND TOUCH THEM TOGETHER over top your head though. You won't be able to use as much weight.
2. Lie on a decline bench w/ your head at the higher end. While on your right side, take a dbell, and with the left arm somewhat bent, lift it from your hip to overhead. Back down & w/o touching, back up. Switch sides. One arm lying side lateral raises. You wont be able to go heavy at all on these either. Try starting w/ like 15 or 20's and focus on form. These 2 are a step beyond just regular side laterals imo. Give 'em a try & let me know.
