Incline Dumbbell Press - Phase 3 - Hypertrophy Phase 1 - Day 2. This exercise helps build the upper chest. Whilst it works the whole chest, it targets the upper chest giving your pecs a fuller appearance. For best results (and to mimimise injury) control the dumbbells and squeeze at the top of the movement. Make sure your head and back make constant tension with the bench.
