obviously everyone here wants to improve their singing but with all the fundamentals aside like posture and breathing , do the warm ups and rest of the videos actually improve singing or do they basically just teach you how your body and voice should be in order to sing correctly?

if that made sense, Thank you btw the lessons are amazing and im here for a whole year !

Hi, Danny! Glad you're enjoying it. 

Your singing will improve the more you learn and practice, similar to any skill or sport! Each warmup routine and tutorial focuses on something different, so you can become a well-rounded, diverse singer with a wide skill set.
