Integrated Fitness WOD Workout

Skill:
OHS - 6RM (105#) went lighter to get 6 good reps due to back

WOD:
8min AMRAP
3 - Full Cleans (135#)
4 - Ring Dips
5 - Box jumps (24")

7 rounds + 1 PC before I tweaked my lower back again with some horrible form. Tweaked back with about 45 seconds left. Wasn't able to go any further.
