Leaning Dumbbell Lateral Raises
Our inclination for Dumbbell Lateral Raises is to grab the heaviest Dumbbell possible, bend our elbows and try to take flight by flapping our arms up and down.
Instead, try these - grab a weight you can do for 12-15 reps - hold onto a pole or machine and do your Lateral Raises leaning. This will keep you from flailing the weight. This puts the focus on the muscle rather than the amount of weight you're pitching around.
With the lean you can actually bring the Dumbbell higher and get a much better contraction. I bend my elbows slightly and bring the Dumbbell slightly forward rather than crank it backwards.
