The deadlift weight should be manageable to easily string 6 to start the workout. Scale chest-to-bar pull-ups as needed, kipping or banded pull-ups are fine for those who have been progressing. If you are newer, stick with strict banded or ring rows. For the KB step-ups, you may hold the KB anyway you wish, but you must alternate legs stepping up to the box.
7 rounds for time:
6 deadlifts, 225/155#
7 chest-to-bar pull-ups
8 KB step-ups, (4L/4R) 24/20″, 53/35#
