It is 6 exercises. Starts with G4 chromatic descent then back up, all done soft and slow. Rest 3 minutes!!! #2 was slurring 4ths down to F#-C# then up. Rest 3 minutes!! #3 was a soft staccato from first space F to fourth line D, ⅛ notes up 16ths down. 4 minutes rest!!! #4 was intervals up to a 6th slurred in 7/4!! Again, go down then up! 5 MINUTES REST!!! #5 is slurring G4-G5 using triplets in 7/4, up then down. Rest 5 minutes. Last exercise (phew) is a range/scale exercise playing 1-2-3-5-8-5-3-5-1 in all keys up to C6. To develop range, rest (no time given) then do so as high as possible! NO WONDER YOU THOUGHT AS YOU DID!!!! It's 20 minutes of resting. I do it when I'm driving to rehearsal. Your lesson had to be at least an hour! Regardless of who's warm up I've seen, they all start with the basic theme of Moecks #1. Even the 40+ year old exercises from my teacher are very similar and they predate Moecks. That's why I said the Plog was too advanced.
