Tip: Neutral Grip Single-Arm Dumbbell Bench Press

If you can bench press two 90 pound dumbbells, you should be able to single-arm bench press a 90 pound dumbbell. If not, your core is too weak.

This is one of the best anti-rotation exercises out there, and you get some extra chest, shoulder, and triceps work along with it.

If your core is strong, you shouldn't have any drop off in strength between your two-arm dumbbell bench press and your one-arm dumbbell bench press.
