The side plank lateral raise is an exercise that combines an isometric side plank hold with a dumbbell raise to target both the core and the shoulders. You probably won't be able to use much weight without disrupting your balance, but even at light weight, this is a movement that can help address multiple muscle groups in a time-efficient workout.
