lol, i just couldn't make out his translation, i had a pretty good idea of what he was talking about there.
I used to worry about such problems, but i'm young so meh...... shred now, pay later.... lol no seriously i try to remember to warm up, but it's hard, i usualy just plam mute some metal songs to get my right hand going, then run up and down some neck long sweeps to get the left moving, and i actually ach if i try and go to fast to soon, but once i get going!!!!!! mmmmm shredderiffic!!!!!
speed trick.... the 1-2-3-4 trick is always anoying to make ur parents listen to, u play those 4 frets alternate picking on each string, then 2-3-4-5, 3-4-5-6, so on so forth allllllll the way up the fret board, then go backwards all the way back 24-23-22-21, 23-22-21-20...... by the time u get back to the nut, ur warmed up. do it for 40 mins and u'll notice immediate speed improvements. all it's doing is sinking ur 2 hands up which u need to sound good when ur trying to do a vai, or gilbert run... another one is alternate pick a sweep scale as fast as u can (starting slow) and try to control urself then gradualy allow ur hands to move faster, and try not to get into sweeping for as long as possible...
when i was in high school and i did alot of weights for sports teams, i found it made my forarms waaaaaaaaaaaaaaaaay to tight and i couldn't play for ours after working out (yes i stretched before and after practices) but that's just me... i like to have loose forearms when playing.
