@saraila Your list will change. Murph isn't that bad, just grindy. My personal worst WODS are:
Ugly Sweater
2 rounds
90/70 Calorie Row
70 Wall Ball Shots (20/14)
50 Power Snatches (55/35)
30 Burpee Box Jumps (50/60 cm )
We did this in a full class, only 2 of us got back on the rower the 2nd time.
Linchpin Test 13
For Time
400 meter Run*
20-19-18-17-16-15-14-13-12-11-10-9-8-7-6-5-4-3-2-1 Burpees
Wear a Weight Vest (20/14 lb)
Kalsu is probably the worst but I'll never do it.
