You've been building your back for the last five weeks. You're getting closer to the finish line. Celebrate with an extra set of pull-ups to make your traps even more pronounced. Do as many reps as possible, but make sure to maintain proper form.
At the bottom of each rep, your arms should be fully extended. Concentrate on squeezing your shoulder blades back and at the top of the movement, and make sure your chest touches the bar on every rep.
We like big backs and we cannot lie.
