Ha ha..
No, I don't usually do them all at once. Ya gotta understand, I've been working out for a LOOOOONG ass time. I get bored, so I may only do a few sets of one exercise or I may do one and just keep switching stations.
I work out at a fast pace. Always have. My shoulders barely get sore. I used to swim for the U.S.A swim team for years. I started out swimming butterfly when I was a little kid because nobody else wanted to. My shoulders became very accustomed to endurance training as I would swim fly for up to two hours almost non-stop.
Since I don't really believe in lifting super-heavy for the delts, I have to kick up the volume. I can fly through a workout like that without really wasting any time. I hate cardio, so keeping moving really helps. I have a fast metabolism and I don't like bullshitting at the gym... once I start, I can't stop.
Technically, I am 'juicing' since I am on legit HRT and have lab work done once every three months.
I do know what overtraining is, and when I feel like I am overdoing it, I just take a few days off.
I know the anatomy of the shoulder joint (rotator cuff) thoroughly, so I don't feel I am being counter-productive at all. To be honest, you could pull a few of the exercises out and it would probably be more accurate.
I remember years ago reading how Vic Richards would blast certain muscles-- and if he felt like it, he would blast them again the next day. My workouts have always been unorthodox. I have kept training journals since the day I started working out. The only consistency I can see is in keeping the journals themselves...
How's that for ambiguous?
