Nemeo’s take

This exercise is similar to the military press with dumbbells but in an alternating version, it amplifies the instability and the stress on the center of the body. This is a good compromise for strengthening each shoulder independently, but core stability and forearm fatigue can limit overload in the long term. For pure hypertrophy, it remains a step below the guided press on the bar or on the machine, but it shines for muscular balance and the prevention of imbalances.
