Routine

 Ive been doing the daily routine , well daily and right after ill do the tutorial to improve my range. is this to much practice at once? and  it is possible to do the improving range tutorial alone since it comes with a warm up?

If you don't feel sore or fatigued, then it's technically not too much! But I'd encourage you to also spend time learning songs and rehearsing them. We always want to apply our vocal technique to actual songs!
