Front Squats, Burpee/Box Jumps

After heavy Front Squats, we followed up with a nice metcon of moderately heavy front squats. I have been trying to add factors to my wods to make them more difficult lately. A regular factor is the addition of a 20 lb weight vest. The Workout:

7 rounds for time of;

7 Front squats @ 185 lbs.
7 Burpee box jumps

Time: 15:13 at 185 and 155 (20 lb weight vest worn the whole time)

I started the wod at the prescribed weight. I barely made it through 3 rounds. We dropped the weight to 155 for the remainder. The bar weight included the 20 lb weight vest.
