This is more a recommendation than a typo. And yes, a minor detail.
In this gym message, "hand-eye co-ordination" should be "eye-hand coordination".
There's representation in "hand-eye", but "eye-hand" is more common and has international representation.
The term "co-ordination" also has linguistic representation, but doesn't have the wide technical representation for this specific example of "motor coordination" (as for example, Developmental Coordination Disorder). Yes, there is "motor co-ordination" in the scientific literature, but it represents less then 10% when compared to "motor coordination".
As I said, minor detail :)
