Today, you'll perform the same back routine you did on Week 1, starting with high-tension pulls like the renegade row, advanced pull-ups, and the deadlift to-bent-over-row, then polish off your biceps with curls from every angle.
The rules we applied to the weighted dips two days ago also work for weighted chin-ups. Use a weighted vest, dip belt, or hold a dumbbell between your ankles. If bodyweight chin-ups are enough to make 8 reps difficult, forget the extra weight. If you need extra help, jump on a pull-up machine, grab a band, or do jumping pull-ups.
