What is the correct hand placement when spotting the dumbbell fly exercise?

Spotting near the biceps positions the spotter too far from the actual load, reducing the ability to quickly stabilize or redirect the dumbbells if the client loses control.

Positioning hands close to the dumbbells or wrists places the spotter at the point of greatest mechanical risk - where the load is furthest from the body during the fly arc. This placement allows the spotter to immediately take the load if the client loses grip or control without interfering with the natural movement pattern. Avoiding contact unless needed ensures the client performs the full exercise unassisted while safety is maintained.

Maintaining contact behind the elbows throughout the descent is overly interventional and interferes with the client performing the movement independently, which is contrary to proper spotting protocol.

Keeping hands at the sides in a ready position with elbows at 45 degrees does not place the spotter in a biomechanically effective position to rapidly assist with the dumbbells during the exercise.
