You don't manhandle several hundred pounds of loaded barbell the way this man does without having some serious strength, and conditioning.
Start training the overhead squat, and let me know when you get to the point that you can perform 1 rep at bodyweight.
Try to push press a snatch grip BW overhead.
Try to front squat 300+ or even 400lbs
Try working pulling movements 5-6 days a week.
