The lateral heads of my shoulders seem to be pretty weak. I can't pull off side laterals with the lightest dumbells I can find (7 KG). Obviously I'm just starting out and am looking for ways to get my shoulders stronger... Weirdly u would think I would be weak as water for that weight, but my shoulders actually look quite broad...

What do you suggest I do? Stick to compound movements like the military press until my delts are stronger? I can't finder any lighter dumbells than the 7s.

At the moment my shoulder routine looks like this:

Dumbell Shoulder Presses 3x8
Smith Machine Presses 3x8
Dumbell Front Raises 3x8
Reverse Pec-Dec 3x8

Any suggestions would be greatly appreaciated....
