Is Incline Or Flat Bench Harder

The bench press is undoubtedly the iconic movement in the gym for measuring upper body strength. However, when it comes to the Flat Bench Press and the Incline Bench Press, many fitness enthusiasts fall prey to a common question: which one is harder? This question is not a simple 'yes' or 'no' answer, but involves a number of aspects including muscle recruitment, biomechanics, and personal training habits. This article explores the differences between these two forms of the bench press, with the aim of providing readers with a comprehensive and in-depth perspective that will help them to better understand and choose the right form of training for them.

Differences in Mechanism of Movement and Muscle Recruitment

Firstly, we need to understand the fundamental difference in the mechanism of action between the flat bench press and the incline bench press. The flat bench press is performed on a horizontal bench, and the main target muscle group is the entire pectoralis major, while the triceps and the anterior deltoid are also recruited as secondary muscle groups [5]. Its trajectory is relatively straightforward, with the barbell or dumbbell moving vertically up and down, providing a more uniform overall stimulus to the pectoralis major, which is particularly critical for the development of thickness in the middle of the pectoralis major.

In contrast, the upper incline bench press is performed on an inclined bench, usually with an incline angle between 30-45 degrees. This change in incline angle allows the upper incline bench press to exert more pressure on the upper pectoralis major and anterior deltoid [5]. This means that there is a significant increase in the recruitment of the upper pectoralis major muscle when performing the upper incline bench press, which is essential for the creation of a full chest shape, especially the upper chest line. Also, due to the change in angle, the anterior deltoid fascia will be more involved in the movement.

Difficulty Considerations: Power Output and Stability

From a power output perspective, it is generally recognised that the upper incline bench press is more challenging than the flat bench press. This is mainly because the upper pectoralis major and anterior deltoid bundles are required to carry more load at an incline angle, and these muscle groups are typically not as strong as the middle pectoralis major and triceps. As a result, many people will find that the maximal power output of the upper incline bench press is lower than the flat bench press for the same weight. A discussion on Reddit also noted that the upper incline bench press machine is more difficult to push up more weight than the flat bench press.

In addition, the upper incline bench press requires more stability. In the inclined position, the body's centre of gravity changes, requiring stronger engagement of the core muscles to maintain trunk stability. If the core is not strong enough, it may cause the body to sway, affecting the normality and safety of the movement. The flat bench press, on the other hand, requires relatively less stability because the body lies completely flat and has a larger support area.

The influence of personal training habits and experience

It is worth noting that the 'difficulty' of the movement is not set in stone, but is also influenced by individual training habits and experience. As one user said, 'Theoretically it's all about the upper incline being harder, but in reality it's all about which one has trained less and which one has a harder time pushing 100kg.' If a person has trained for a long period of time, it's not always easy to get up to 100kg. If a person focuses on the flat bench press for a long period of time and rarely performs the upper incline bench press, they will naturally not perform as powerfully on the upper incline bench press as they do on the flat bench press, and thus feel that the upper incline bench press is more difficult. And vice versa.

Therefore, for novice fitness practitioners, it is recommended to start with the flat bench press, master the correct movement pattern and muscle power sense, and gradually build up basic strength. With the accumulation of training experience, then gradually introduce the upward incline bench press, in order to fully develop the chest muscles. At the same time, you can also try reverse-grip flat bench press, and some studies have shown that reverse-grip flat bench press can train 30% more upper pectoral muscles than ordinary flat bench press, while upward incline bench press can only train 5% more upper pectoral muscles than ordinary flat bench press. This provides another effective option for upper pectoral training.

Conclusion.

In summary, from a biomechanical and muscle recruitment perspective, the upper incline bench press is often considered a more challenging movement than the flat bench press because of its greater recruitment of the upper pectoralis major and anterior deltoid and the greater demands on core stability. However, the difficulty of the movement is not absolute and is dependent on the individual's training experience, level of muscle development and training habits. Whether it's the flat bench press or the incline bench press, there are no absolute advantages or disadvantages, the key is to arrange the training programme according to your own training goals and physical condition, and to ensure that the movement is standardised. Only in this way can you maximise your training results, avoid injuries and ultimately build the ideal chest muscles.
