CrossFit 17.2: Back To The Dumbbells

Were you thinking the dumbbells were gone for 17.2??  I was sure hoping so.  But NOPE, here they are again.  The Open 17.2 Workout was released and we are back to a 35lb dumbbell for women and a 50lb dumbbell for men.  This time however we are lucky enough to have two.  

Complete as many rounds and reps as possible in 12 minutes of:
2 rounds of:
  50-ft. weighted walking lunge
  16 toes-to-bars
  8 power cleans
Then, 2 rounds of:
  50-ft. weighted walking lunge
  16 bar muscle-ups
  8 power cleans
Etc., alternating between toes-to-bars and bar muscle-ups every 2 rounds.

Men use 50-lb. dumbbells
Women use 35-lb. dumbbells
