3 Rounds of 400 Meter Farmers Carry Workout

Warm up:
Row for 5 minutes

Strength:
5X5 135 Back Squat

WOD:
3 Rounds of 400 Meter Farmer Carry w/ 45lb dumb bells. Everytime the weights touch the ground, do 5 burpees

I had originally planned to do this as 5 rounds and at 55 lb. It was absolutely miserable. It was adjusted before and during.
