1-armed cleans, snatches, overhead presses and overhead squats all work, both with DBs and maybe also BBs. Also, most bodybuilding movements work unilaterally; bench, row, curl etc. You could do old time stuff, like turkish getups, suitcase deadlifts and bent press. You can do sprints or jumps with a weighted vest, pistols (with a weighted vest) or glute ham raises. Sled dragging obviously works.
