Hello

I'm having difficulties with the spider warm up. I appreciate its importance in stretching and finger memory and it's not clear to me where to place my thumb and the angle to keep my hand at when doing this exercise at different points on the fret board.

For example, I think that my hand and thumb position needs to be angled differently when doing spider at 4tht finger 1st fret 6th string Vs 1st finger 6th fret and 6th string. I'm worried that I'm improvising with hand and thumb position to hit strings cleanly and drilling in bad practice. Can you provide more advice on hand positon and finger placement for the hard to reach parts of the fretboard please?

Thanks in advance

Andy
