What’s the Best Exercise for Chest Growth?
Posted by Dayne Hudson

The idea of pre-exhaustion training makes sense; begin with an isolation exercise right before a compound exercise to "pre-exhaust" the muscle and prime it ahead of the next lift. The muscle will therefore be activated and more prepared for a maximal change in strength and size.
For example, Bulk Nutrients customer Gerry performs dumbbell flies (isolation movement) for his chest, before moving into a bench press (compound movement).
But sadly, according to science, this doesn't work.
This study utilised thirty-nine trained subjects (nine male and thirty female) who performed resistance training for 12 weeks. They were split into three groups:
The researchers found no significant differences in strength or body composition. They concluded:
"Pre-exhaustion training offers no greater benefit to performing the same exercises with rest between them compared with exercises performed in an order that prioritises compound movements."
But what happens if we pre-exhaust the supportive muscles ahead of a compound lift? Does that make a difference?
And what if we rest in between the isolation movement and compound movement, and don't jump right into the compound movement like in the previous study?
Well, this study investigated these very things, by having subjects do the following BEFORE a bench press movement:
And this was all after a session where their one-rep max was determined on the flat bench press. Moreover, the subjects had at least 3 years of resistance training experience, which is terrific when considering the validity of the results.
So, what did they find?
No differences in chest activation.
But interestingly, what they did find, was that the triceps were worked harder with the pre-exhaustion routine.
With this in mind, if you like to train chest and triceps together, then performing a lying triceps extension ahead of a bench press is suitable.
So, we know pre-exhaustion won't help us, but other research into maximal chest activity tells us that dumbbells are likely better than their barbell alternatives.
This was discovered amidst research that examined tricep extensions prior to these chest exercises:
All bench press exercises were done at four sets at their 10-repetition max. The tricep extensions were done on the cable pulleys, performed at 4 sets with their 10-repetition maximum load. The 19 healthy male subjects rested two minutes in between sets and exercises.
And they found:
So practically speaking, dumbbells are the best at isolating our chests and should feature in our chest workouts.
This is because it doesn't call upon our front deltoids and triceps as much.
However, given the barbell bench presses call upon both the front deltoids and triceps rather well as noted in the research, that may be the best for overall upper-body development. The smith machine should really be left out of your routine, given it doesn't seem to isolate the chest well at all.
A great series of exercises for the chest could be:
**(sets and reps are dependent on your lifting experience).
The bottom line is that the current body of research points to pre-exhaustion training NOT increasing chest activation, muscle growth, or strength. Moreover, dumbbells are better for chest activation, whilst barbell bench presses are better at calling upon your front deltoids and triceps.
For this reason, barbell bench presses might develop the upper body as a whole better than dumbbells. However, a good chest workout will incorporate both. At this point in time, pre-exhaustion training is not recommended to enhance muscle size.
