This is a very short Open workout (7 min), and in these types of workouts, you need a more extensive warmup. Make sure that you have got the heart rate up at least once before you begin. At the early reps, you will feel like a race horse coming out of the gate and will probably hit a wall nearing the 9 rep scheme. Have a plan set of how many reps you can string together before you need a break. This workout does not leave you a lot of rest time other than your transition between exercise, so try to minimize your rest time between sets. Take a quick breather, count 1,2,3 and get back on the barbell or pullup bar. Try to save your grip by using the hook grip on the cleans.
