Bear with me while I explain the nonsensical subject title. 
I've had my electric guitar a few years now, but I've only really started to learn play it properly the last month or two so I am still very much a beginner. I have a one to one tutor which is all well and good and when I am at home I practise as much as I can.
Now the point of this thread. I have a lot of quiet time at work and a lot of free time sat on the train to and from work where I can't actually practise on my guitar. What's the best way to spend this spare time to help me improve, but without actually playing? As I learn mostly from material from my tutor, I don't really have a lot of stuff to read through. I bought a guitar magazine today, but that's not going to keep me entertained for long. I already listen to a lot of music as well.
