Warm-Ups:

-For all Wind Instruments Long tones are fantastic for building strength and endurance.

-Slow chromatic scales are great for fingering dexterity and they helps build a base with which to improvise a solo. 

-Try the 'Long-Note' contest. With one breath see how many seconds you can play a good sounding note on your instrument! 

-I warm-up my voice by singing a 'softer, easier song' or what I call a 'stressless' song. This is one that's comfortably in your vocal range and that you can sing lightly sometimes maybe incorporating your 'head-voice'.

-Singing pure straight tones with no vibrato builds your pitch center and control for when you do decide to use vibrato.
