Hi!

I am a 30 mins newborn into guitartricks, an a complete acoustic beginner. I am currently on the spider-leg warm up exercises on the beginner tutorial, which consists of stretching my fingers across all frets, but i am really struggling to span across 4 frets an hold the strings down strongly enough to play a clear note. Will this get easier with practice or are there any exercises I can do to help? It is giving me cramp.
