In this video I’m walking you through what I genuinely think is the most effective upper body workout you can do with just dumbbells—back, chest, shoulders, biceps and triceps—using exercises that are science-backed so you can stop second-guessing and just focus on progressing. This is part two of my dumbbell-only series, and it’s designed to work together as a 3-day split so you’re getting enough weekly volume across muscle groups to actually see results. We start the way we always should: 5 minutes of light cardio plus dynamic stretches, because it seriously reduces injury risk and helps you perform better (yes, even on upper body day—your whole body stabilizes your lifts). Then I take you through single-arm rows for a big lat stretch and full range of motion, incline dumbbell press with my sternum test + elbow “arrow” cue, and seated shoulder press for strong delt activation and real-life strength. After that, we hit an arm superset—overhead tricep extensions for that long-head stretch (aka most of your arm size) paired with preacher curls to keep momentum out and tension on the biceps. We finish with lateral raises (humbling, always) and I include pull-ups as an optional finisher with practical progressions, plus a reminder that progress isn’t linear—and we keep showing up anyway.
