"Stop or you'll blow your brains out, or worse yet, your chops!" Woodwind players can always buy more reeds, but brass players can't buy a new box of lips. Easy does it with those non-stop workouts.
You've certainly got a metronome, tuner, and maybe even a decibel meter in the practice room, but how about a timer? You need something that regularly signals that it's time to rest and come up for air. The chops need a break and some fresh blood circulation. Muscles are strengthened by resting as well as by exertion.
Mandatory resting might seem like advice for wimps. Hence, you rarely see a timer in a trumpet player's bag of goods. For us obsessive/compulsive types some sort of stopping device should be a must-have.
Andre is reported to practice many times a day in brief sessions. Vacchiano advised us to put the horn down while the embouchure still feels good. Strategic resting preserves chops while impatient blasting tends to destroy them quickly. Try practicing a little a lot rather than a lot a little.
