Question About Pre-Fatiguing

Ok. So I want to start pre-fatiguing my pecs on chest day.

Do you perform the fatiguing exercises like a normal set, then move on to your primary lifts? Or do you treat it more like a reverse superset with longer breaks between exercises?

For instance, if using db flies to pre-fatigue…do I complete 3-4 sets of db flies then move onto my primary lift (flat bench, incline bench, machine press, etc.)? Or do I do a set of db flies, wait a minute or two then do a set of bench, and repeat?

Thanks!

You can approach it in both manners. Which one would work for you will depend on how quickly your pre-fatigued muscles recover before the next set, or portion of a superset.

I like to move from the fly/peck-deck directly to the pressing motion without rest…superset style. Fly in the 15-20 rep range…presses in the 8-12 rep range.

Thanks man.

I don’t know if this affects the way I would approach this, but my one and only goal is hypertrophy.

So you’re using pre-fatigue as like a warm-up it seems like. Personal opinion, but with pre-fatigue you only need like 1 -2 sets before you hit your “main” lift.
Rep range for the pre- fatigue should be double the reps of your “main” lift. Once again, personal experience.

So first pre-fatigue could be 16 reps with a considerable weight and usually slow tempo, rest the duration of your rest period and hit the flats. If you don’t feel a pump coming on as you mount your “main” lift, hit a second set of your pre- fatigue.

Just an idea.

Just to throw my hat in here, the best pre-fatigue sequence for chest that I have tried is 1 and 1/4 incline chest flyes (eccentric all the way to bottom, concentric one quarter of the way up, eccentric to bottom, concentric all the way up) followed by incline dumbbell presses. I use a very low incline for this.

I like using the pec deck for pre exhaust. I’ll typically do 3 or so sets on the pec deck, then move onto my main lifts.

Why would I want to “pre-fatigue” my chest on CHEST DAY???

Because we all know that every day is really about working arms.

I guess that explains why mine keeps growing.

I’m doing it wrong.

I think that “pre-fatiguing” wasn’t the word the OP was looking for.

What Stu and BlueCollar described is really more about establishing the MMC and ensuring that the pressing movement will focus on the contraction. For me, at least, if I start out with a pressing motion my shoulders and tris will tend to get more involved if I haven’t already warmed up with something that’s a more “strictly chest” movement, like a fly.

Maybe it was, maybe it wasn’t.

I’m not sure…but warming up is on a different planet than “pre-fatigue”. You usually only pre-fatigue a muscle if it is interfering or becoming the optimal mover in an exercise when the goal is another muscle group.

I don’t “pre-fatigue” anything.

I warm up like crazy though now.

Wait…I take that back…I do pre-fatigue my forearms because of the pain I get when curling. That is all I use it for. My forearms fire first (one reason I never had to train them directly) so fatiguing them means they fire less later in the workout when I go heavier on biceps.

I personally find the opposite. I find that if I pre exhaust my triceps before working my shoulders, my triceps end up failing before my shoulders and I get a less than stellar shoulder workout.

But…the whole goal of pre-exhausting them is so they fail first.

You are mad because it did what it was supposed to do?

That is WHY you pre-exhaust a muscle group…so it fails first and doesn’t interfere with the TARGET muscle group.

That is why pre-exhausting chest on CHEST DAY makes little sense.

^Not the explanation most people I’ve known would use.

As multiple muscles work in conjunction on a compound lift, the one that is naturally stronger (larger?) would require more stress (reps? weight? TUT?) to stimulate a response before the smaller ones.

So in the case of chest pressing, an isolation movement such as DB flyes would target specifically the pecs, creating an already weakened starting point when they are called into play during the subsequent pressing motion. Essentially lowering the threshold of the strongest muscle (pecs) to a more level playing field with the others (delts and triceps).

This is a very useful approach when the target muscle (pecs in this case) cannot be adequatelty stimulated due to the limited strength levels of the secondary muscles (tris and delts)

But if a muscle fails… How do you continue? Since if your triceps are no longer able to lock a weight out for you, would a different muscle take over?

? If I am training chest, THAT is my goal. Why would I care about the triceps?

Why would I want to weaken my chest WHEN TRAINING MY CHEST IN PRIORITY??

It would require your shoulders to handle the load with even less help from the triceps. Get it?

That is why you PRE-FATIGUE it.

If MY goal is chest…and my triceps interfere and always take more of the load, I PRE-FATIGUE the triceps so they are more out of the picture when I train chest…so my chest gets more of the load.

That means more chest growth.
