Cool!
Slow and easy, bud. You ain't so young anymore. A great way to screw up chops is to leap right into things too fast, too hard, and too long.
If I may suggest a few things:
1. Long tones, very softly - no more than mf - boring as hell, but that's where you build strength initially.
2. A few minutes of mouthpiece buzzing. Don't stop up the end of the 'piece, either. Just play little songs like "Mary Had a Little Lamb" by ear. Buzzing focuses the tone and gets things right most ricky-tick.
3. Arpeggios and working the overtone series - only up to high F for a few days - don't push it.
4. Then and only then work on your legato and solo playing.
You'd be doing well to put in 30 minutes a day, or as long as your back holds out. It'll probably be physically demanding at first.
Need a sitrep every day!
