There are a few Lateral Raise and Shrug variations you can do to maximize your shoulder and trap training.
The first variation includes performing a shrug, holding it, and then performing a lateral raise. Once you have raised the dumbbell passed 90 degrees, relax the shrug and lower your arms.
The next variation involves performing the lateral raise first, shrugging once the dumbbells have passed 90 degrees and then increasing the shrug as you lower the raise.
