Beyond 531: Cycle 3, Week 5: V-Handle Deadlifts; also tried Sumo Deadlifts (Video)

V-Handle Deadlift (plug in weight: 425)
155/5, 205/5, 265/3
300/3, 340/3, 380/5, 410/3 (3RM)
300/8
  * The third rep of 410 was sloppy.

Sumo Deadlift
155/10, 265/5, 315/3, 315/3, 315/3
  * Below are videos of the set of 265/5 and the first set of 315/3. The exercise felt a little strange, but I don't know if it's due to my form being bad or my inexperience with the movement. My left leg felt really weird during and after the last set of 315/3.
