A. Skin-the-cat practice. Aim for 3 sets of 3-5 continuous, controlled reps. Finish with 3 reps of a 5-20 second German hang. Some good progressions can be found here, from the folks at Gold Medal Bodies (link).
B. With a partner:
10 rounds of 5 double KB/DB deadlifts + a lap of farmer’s carry
60 KB/DB push presses (single arm) – partition work as needed
60 knees-to-elbows
90 hand-release push-ups
90 Russian KB swings
10 laps suitcase carry.
