I picked up my first bike today :)

P.S. Does the clutch hand pain ever go away? My hand has been hurting all day today and yesterday.

Don't worry!  I was the same way hahah.  When I was learning how to ride, I experienced the same thing.  To kinda get used to using that set of muscles, I took one of those foam stress balls and would squeeze it with my wrist in the same position as it would be while riding.  I'd just do as many reps as possible, then switch hands.  I mean, I'm sure it would have gone away by itself after a while, but I was getting impatient, haha.
