Recently I started technique training from the ground up using the lessons from shredtraining.com (great stuff btw). I learned my legato technique just plain sucks and very underdeveloped. The hard part is that my fretting hand cramps up fast, has limited reach (esp. wide 3 note per string legato) and overall lacks endurance. This makes serious practice hard since I have to pauze all the time. I really want to improve my legato since I think it is my weak point that holds my whole playing back. Any tips? Anybody had similair experiences? How did you overcome this? Aside from continuing exercises I already do, are there other things I can consider? Thanks!
