The flat bench press and the incline bench press are fundamental exercises for developing the chest and upper body. Both are compound lifts, engaging multiple joints and large muscle groups simultaneously, making them highly effective for building strength and size. The decision of which to perform first is a common dilemma for lifters seeking to maximize results. The order directly influences the amount of weight you can lift, total volume, and which specific muscle regions receive the most growth stimulus. Understanding the distinct biomechanics of each lift is necessary for strategically planning your workout sequence.
Distinct Muscle Targeting of Each Movement
The angle of the bench is the primary factor that dictates which fibers of the pectoralis major are most activated. The standard flat bench press places the greatest mechanical stress on the sternal head, which constitutes the middle and lower chest. This horizontal position allows for the heaviest possible load, making it a powerful driver for overall chest size and pressing strength. The flat movement also recruits the anterior deltoids and the triceps brachii as strong synergists.
When the bench is set to an incline, typically between 30 and 45 degrees, the emphasis shifts to the clavicular head of the pectoralis major, targeting the upper chest. This elevation requires greater shoulder flexion, which increases the recruitment of the anterior deltoid muscle compared to the flat press. Due to the less favorable biomechanical position, most individuals lift substantially less weight on the incline press. The triceps also contribute significantly, particularly toward the lockout portion of the lift.
Optimizing Sequence for Strength and Performance
The exercise that should come first is the one where maximizing strength and neural output is the priority. High-intensity, multi-joint movements should be placed early in a workout when the central nervous system (CNS) is fresh. A fresh CNS governs the recruitment of motor units and allows for the greatest force production and the heaviest loads to be lifted. Placing the more demanding lift first ensures maximum effort and weight, which is the primary stimulus for strength adaptation.
The upper chest (clavicular head) is often a lagging muscle group and a mechanical weak point. If the goal is to increase the strength of the incline press, performing it first ensures the targeted muscles are not pre-fatigued by the flat bench. Attempting a heavy incline press after taxing the triceps and deltoids compromises the weight lifted on the incline, reducing the specific strength stimulus.
Prioritizing the incline press when the CNS is fresh allows for the highest possible weight for the upper chest. This maximizes the specific neural drive to the clavicular head before accessory muscles fatigue. Conversely, if overall pressing strength, as measured by the flat bench, is the main metric, the flat bench should be performed first. The flat bench is the heavier lift, placing the highest demand on the CNS, and performing it first ensures peak performance for that specific exercise.
The choice is strategic, based on the specific strength goal you are trying to improve. If the flat bench is the ultimate strength measure, it must be performed first to avoid performance drop-off caused by the fatigue of the supporting musculature. If the objective is to improve a weaker upper chest, leading with the incline press is the more effective strategy.
Modifying the Sequence for Specific Training Outcomes
While strength optimization dictates leading with the most challenging lift, the sequence can be intentionally modified to achieve specific training outcomes like hypertrophy or to address muscle imbalances. If maximizing total volume for the larger sternal head is the goal, performing the flat bench press first allows you to handle the highest possible cumulative weight and repetitions. This high-volume flat work is a powerful stimulus for overall muscle growth in the middle and lower chest.
Another effective sequencing strategy is the pre-exhaust technique, used to intentionally fatigue a specific muscle before moving to a heavy compound lift. For instance, a lifter could perform a lighter, higher-repetition incline dumbbell fly or press to fatigue the upper chest before moving to a heavy flat barbell press. This ensures the clavicular head is the limiting factor during the subsequent heavy flat press, maximizing its recruitment for hypertrophy, even with a slightly lighter load.
The order can also be adjusted to accommodate structural or joint concerns. If a lifter experiences shoulder discomfort with the flat bench but finds the incline press more comfortable, they may choose to perform the incline first. The incline press can serve as a comprehensive, heavy warm-up for the flat bench, ensuring the shoulders and elbows are fully mobilized for the heavier, more demanding movement. Ultimately, the sequence should be dictated by the user’s current goal.
