Summary- A foot pedal shows the perfect ergonomic design
Independent Movement - By allowing the arms to move independently of each other, It delivers the ability to balance the workout when one arm is weaker or injured which encourages symmetrical strength development. Independent motion also allows for bilateral reciprocal training.
Start Adjustment - Unlike many other shoulder press machines, It does not use a foot kick plate to help the arms get into the proper position to begin exercise. The seat adjustment feature also allows taller users a wider grip.
