'Front Raises' primarily strengthen the anterior shoulders (deltoids) but also target your chest (pectorals), abdominals, and biceps as secondary muscle groups. Recruiting many muscles in the anterior chain, this workout helps define all the frontal muscles of your upper body as they work together as a cohesive unit. The front raise will help you get that lean boulder shoulder look, working the front delts and targeting the sides too. Like the overhead press, this exercise is great for relieving muscle tightness when performed over many repetitions.
