Hey Folks , Just upgraded to full access acount and need some help , I'm currently in chapter 2 of guitar fundamentals 1 and need to know if there is any exercies that i can do to help my fingers .

I'm right handed and have no problem curlng my Index and middle fingers but often when i am trying to play a chord and it covers 4 frets my ring finger and and pinky often has trouble trying to curl and reach some of the strings .

Will my fingers with curling and stretching improve over time as I practise ?
or is my guitar the problem ?

here is a link to my robson guitar which has a big body but the neck is alright if you ask me but I am a beginner after all hehe .
