  1. **The values of the chest EMG graph at 2:22 are incorrect except for the barbell bench press (my apologies for the oversight). Here's a picture of the original graph with the right values for your reference: https://builtwithscience.com/graph-fix/ . Also, for those who've been asking, although the dumbbell press may have underperformed compared to the barbell bench press in this study, it's not that big of a difference and other EMG analyses have found quite similar chest activation between the two. So if the dumbbell press is a more comfortable movement for you and you feel a much stronger contraction with it, feel free to use that as an alternative. I'll discuss more about the benefits of dumbbell chest presses in workout B! Stay tuned 🙂
