Saxophone breathing question?
I’ve only taken up sax a few months ago. When playing I find that when my lungs get fatigued, exhaling relieves it, not inhaling. Is the main root of this problem that I need more lung strength, or that I need to practice exhaling all my air quickly before taking in new air during a song, or do I need to do something else?

Since you started only a few months ago, you’re still getting used to playing saxophone.

You’ll build up lung strength as you play.

A good exercise is called doing ‘long tones’ where you play notes for an extended period of time.

One exercise I do takes about 8 minutes. I spend one complete breath split between two notes. Then progress up and down chromatically one octave from low E to E.
