A powerful physique isn't complete without a strong back. But if you've been largely relying on cable machines to build yours, you're almost definitely leaving size and strength gains on the table.

If you're not great at pull-ups, those around-the-world pull-ups may be impossible for now. That's totally OK. Regular or assisted pull-ups will get the job done for now. But the advanced variations are a great goal!
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.
