thx for replay at last one to help me bit with this , i got some more questions by the way ..

1.should i be aiming for top speed of those exercises im doing like 160 bpm or more or should i be moving on new exercieses every new week ..

2.i hear all about relaxation and slowing down i do that and after a while i can feel burn in my forearm muscule i dont know if i started strugling or it's just natural feel to my hand after that i try to relax and even i focus more on relaxing the hand even tough im aware of playing the exercise as needed should i stop there and take some rest i do that but i dont know if i do it right..

3.Is it natural feel that i dont rly much see improvement let's say after 2 days of plaing one same exercise , i dont see much but a little rly little change mby , is that natural and how long roughfly speaking it takes to develop some control over one constatnt tempo let's say 120 bpm or even more after practice..

4.you say 4 exercises per day , and do tham for a week than move on new one , should i get back on the old once sometimes or after nailing those down move on the next and dont get back till i end the book (some day i hope :D )..

that's all any other tips are welcome so i can improove faster i rly want to be able to play fast in 2 years if possible with correct practice ofc.

Im already good guitarist and i can solo some but not shred fast i rly love shreding.. :)

thanks i know 2 years sounds lame but let's be real with correct practice and 6-7 h per day i think it's rly possible, btw im not beginner i already play let's say 50% good and for 100% i need some more practice..
i also have good sense of rytham i can catch melody on air i can play along improvise on every rytham i hear i realy fast can adopt to any kind of melody..i think my ear is good trained so far.. and i got some speed , but not the one im aiming for .. ofc quality not quantity i know that but fast playing with quality makes it perfect..

Practice makes it perfect !

Thanks! :D
