This page is not medical advice or a rehabilitation protocol. Ely's personal review applies to purchased workout plans and does not replace an in-person assessment by a licensed healthcare professional.
The iso-lateral shoulder press machine lets each arm work independently through a guided path. This exposes and addresses strength imbalances that bilateral machines hide. The independent arms mean your stronger side can't compensate for your weaker side.
When to use it
Use for balanced shoulder development.
Who it's for
All fitness levels looking to build strength and muscle definition.
Pay attention to which arm fatigues first—that's your weaker side. Match your stronger arm's reps to your weaker arm's capacity rather than letting the strong side do extra. You can also use single-arm work, pressing one arm while the other rests.
