Work up in sets of 3 bench press – focus on a controlled descent and a fast return up keeping those shoulders retracted.
If needed scale deadlift weight to a moderate weight – around 60%. For burpees, make sure you are perpendicular to the barbell when on the ground. This metcon is designed to be fairly quick.
