Each time I practice I do warm up stretch exercises. One exercise Spider Legs that Lisa teaches I have the following problem:

I'm unable to position my hand/wrist properly in order to place one finger at a time on frets 1, 2, 3 my and leave them there no to lift fingers. My wrist does not stay straight, it angles and I find my fingers partly laying on the strings instead of the finger tips. 

I have no problem placing each finger tip on the frets one at a time but I must lift each finger - index finger on fret 1 lift, middle on fret 2 lift, place ring finger on fret 3 lift. 

Is that incorrect if I place my fingers one at a time on each fret ? I can successfully play each note clean but only if place my fingers as noted.

Thanks,

Bob
