Just found the website and I have been trying to make my way though the fundamental section but I find that my left hand/forearm are killing me after only a bit of playing.

Do I just need to build up more strength?

I've been trying to hold the guitar properly but it just doesn't feel right. It always seems to slide down into my palm and just rest there.

So should I continue forcing myself to play with some discomfort and hope that it gets better or just do it how it feels comfortable?

Also is there any particular guitar that I should be learning on? I have a fender acoustic that was a package set. It seems big and bulky to me.

Great site so far!

Thanks
