The reduction in strength observed by Saeterbakken & Fimland (2013) may be the reason for inferior EMG amplitudes, and this may therefore be a reason why using an unstable surface produces a less effective training stimulus
for the pectoralis major.
This section provides a summary of the electromyography (EMG) activity studies into resistance training exercises
for the pectoralis major.
During a four month span in that deployment, Drs. Salazar and Choate treated nine male patients (four Army, five Air Force)
for pectoralis major tears.

for short).

However, there are many ways to manipulate your routine and training intensity
for the purpose of overcoming lower pecs shallowness and adding more volume to your chest such as using dropsets, rest - pause sets and negative reps. And if you want a well - developed chest, hitting both the lower part of the
pectoralis major and the
pectoralis minor is a must.
To recruit the
pectoralis minor more, opt
for parallel bar dips and decline bench presses, the latter of which produce superior results
for lower pecs hypertrophy when compared to using a flat bench.
The only muscles that do not receive direct stimulation are the
pectoralis major muscles of the chest or pecs
for short.
As one of the best moves
for building a stronger and bigger upper body, it effectively targets many of the same big upper body muscles as the conventional version — the clavicular head of the
pectoralis major, the anterior deltoid and the triceps — only from a different angle, which contributes to shifting a major part of the work to the upper chest and shoulders.
While watching the NBA playoffs, I do exercise
for lymph drainage (running on a trampoline) and mobility (sofa smash, gut smash,
pectoralis release, and strengthening).
Plyometric push - ups will quickly activate your fast - twitch fibers, which are responsible
for producing short bursts of power, and help you build explosive strength in your
pectoralis major, deltoids and triceps.
The sternal (lower) region of the
pectoralis major does most of the work
for your chest with some help from the clavicular region.
The big culprit
for shoulder pain is often
pectoralis minor.
These regions of the
pectoralis major have to be targeted specifically
for optimal growth.
In the sports world cyclists and baseball catchers are at risk as they have to hold postures
for long periods as well as the amateur bodybuilder who over develops and tightens the
pectoralis (chest) muscles neglecting the muscles in the upper back.
Sticking with the bench press as an example, it may only consist of the
pectoralis muscles, the deltoids and the triceps but the
pectoralis is a massive muscle (comparatively
for the upper body) but this explains why it is one of the best measures of upper body strength there is available.
Through his understanding of the anatomy of the human musculoskeletal system and exercise dynamics, and also from his 50 years of experience training thousands of guys at his gym, Vince came to the conclusion that the neck press, which involves bringing the weight down to your neck, while flaring your elbows out to the sides, stimulates the fan - shaped
pectoralis major muscle of the chest better than the regular bench press, or almost any other exercise
for that matter.
Major muscles used in the chest press machine are
pectoralis major, minor, serratus anterior, anterior deltoid, all three heads of the triceps, and forearm muscles
for grip and stabilization.
The other two - thirds of the collarbone serves as the launching point
for the uppermost fibers of the
pectoralis major.
The pre-exhaustion method might not be an effective technique to increase the extent of neuromuscular recruitment
for larger muscle groups (e.g.
pectoralis major
for the bench press) when preceded by a single - joint movement (e.g. pec - deck fly).
The front shoulder muscle group is usually a secondary muscle group used
for many exercises, especially those involved directly in the
pectoralis region.
This exercise is excellent
for stretching the
pectoralis major and
for working on the flexibility of the shoulder girdle.
In direct contrast, the
pectoralis major has a very large shoulder horizontal adduction moment arm length, making it easily the most effective muscle
for moving in the opposite direction.
In general, it seems that compound exercises that include shoulder horizontal flexion feature as the best exercises
for creating overall
pectoralis major activity.
Ackland et al. (2008) showed that the
pectoralis major (superior sternocostal head) displayed a peak moment arm length
for shoulder adduction at 41 degrees (length = +32.9 mm) and a minimum at 120 degrees (length = -17.7 mm), while the
pectoralis major (inferior sternocostal head) displayed a peak at 64 degrees (length = +33.6 mm) and a minimum also at 120 degrees (length = -16.2.
Indeed, the
pectoralis major has longer moment arm lengths
for shoulder horizontal adduction (also called shoulder horizontal flexion) than any of the other chest muscles, indicating it is the prime mover
for this action (Keuchle et al. 1997).
Since the other prime movers (including the triceps brachii) did not display such close relationships with increasing bench press strength, these findings demonstrate that the bench press is an ideal exercise
for increasing the size of the
pectoralis major muscles, particularly when a wide grip variation is used.
The flat and decline variations of the bench press appear best
for developing the sternocostal head of the
pectoralis major.
Therefore, it seems that despite their popularity, unstable surfaces are likely not suitable
for training the
pectoralis major.
