One Arm Dumbbell Side Lateral Raise - Phase 2

One Arm Dumbbell Side Lateral Raise - Phase 2 - Day 1 - Strength. Complete the One Arm Side Lateral Raise with a warm up set of about 8 reps, before the working set of 10-12 reps. This exercise will work mainly the medial or side head of of the deltoid, but will also bring in the front & rear deltoid slightly as well as the trapezius to stabilise. Keep the weight controlled throughout the movement and avoid swinging for best results. Nick Jones - World Bodybuilding Champion & Joe Grima - IFBB Bodybuilding Champion
