If you are uncomfortable using a barbell, use a kettlebell or dumbbell and perform 2 x single-arm clean and jerks with each arm. Choose a challenging weight. It should be heavy enough that it requires you to generate extension through the ankles, knees, and hips (i.e. jump) to receive.
Use the extra time for recovery between rounds – The attempts should be explosive, so you want to maximize muscle recovery (ATP).
Substitute knees-to-waist or v-ups for knees-to-elbows.
Set the clock to 30 intervals of 30 seconds of work and 10 seconds of rest
