Train hard and stay strong, but don't forget to ask for help when you need it. If you're not used to busting out consecutive sets of pull-ups, today could be extra challenging. That's OK. See the challenge as a chance to grow rather than a difficult obstacle. If you're training with a buddy, opt for partner-assisted pull-ups. No partner? Try using a box, and practice progressively working up from jumping pull-ups.
You should be familiar with dropsets by now, but check the technique page if necessary. Today contains a tough dropset on nearly every exercise, so get ready for a massive pump in your back and biceps.
