Full vs Partial Range Bench Press: What the Research Shows About Strength Gains

If you've spent time in a gym, you've probably seen lifters loading up a bar and pressing it just a few inches up and down, never bringing it close to their chest. It's a common sight, and some lifters swear by this partial range approach for moving heavier loads. But does limiting your range of motion on the bench press actually lead to better strength and muscle adaptations? A published study set out to answer that exact question — and the findings offer some useful insight for anyone serious about building strength.

What This Study Examined

The central research question was straightforward: does the range of motion used during the bench press affect neuromuscular adaptations over time?

Specifically, researchers wanted to understand whether performing the bench press through a full range of motion produces different results compared to partial range of motion variations. The study was focused on neuromuscular adaptations, which refers to the combined changes in both the muscular and nervous systems that occur as a result of resistance training — things like increased muscle strength, hypertrophy, and improvements in how efficiently the nervous system recruits muscle fibers.

This is a meaningful question because range of motion is a variable that lifters frequently manipulate, often without a clear understanding of how it affects long-term training outcomes.

How the Study Was Conducted

The study compared participants who performed the bench press using a full range of motion against those who performed partial range of motion variations over a prolonged resistance training period.

While the abstract provided does not include the full breakdown of participant numbers, group assignments, or the exact training volume used, the study involved a resistance training protocol extended over a significant duration — long enough to allow measurable neuromuscular adaptations to develop. This is an important design feature, as shorter studies sometimes fail to capture the full picture of how training variables influence adaptation.

Measurements focused on neuromuscular outcomes, meaning the researchers were tracking both the muscular and neural changes that occurred as a result of each training condition. This type of measurement goes beyond simply asking "who lifted more weight" and instead looks at how the body itself adapted to the training stimulus over time.

Key Findings

Based on the study, the primary finding was clear:

• Full range of motion bench press produced greater neuromuscular adaptations compared to partial range of motion bench press after prolonged resistance training.

The results suggest that training the bench press through a complete range of motion — bringing the bar down to chest level and pressing to full extension — leads to superior adaptations in both the muscular and nervous systems over time.

Partial range of motion work, despite allowing heavier loads to be used, did not appear to match the full range of motion condition when it came to the neuromuscular changes that occurred over the course of the training period.

What This Means for Training

Taken together, these findings suggest that prioritizing full range of motion during the bench press may be a more effective strategy for building long-term strength and neuromuscular fitness than defaulting to partial range work.

This aligns with a principle that many experienced coaches already apply: that moving a muscle through its complete range of motion tends to produce more thorough adaptations compared to training within a shortened or restricted range. The study adds a layer of research-backed support to that coaching practice.

For everyday gym-goers and athletes alike, the practical takeaway is worth considering. If your goal is to develop genuine strength and neuromuscular adaptation from your pressing work, cutting the range of motion short may not be the shortcut it appears to be. The ability to move more weight through a partial range doesn't necessarily translate into superior adaptation when compared to controlled, full range repetitions.

It's also worth noting that technique matters here. A proper full range of motion bench press requires shoulder mobility, stability, and good control throughout the movement. Working with a qualified trainer — such as those available through Atlas Personal Training in Reno — can help ensure you're executing the movement correctly and getting the most out of every rep.

That said, partial range of motion training isn't without its uses. Some coaches include it strategically for specific goals like overload training or addressing sticking points. The research simply suggests that as a primary training approach, full range of motion is likely the more productive choice for neuromuscular development.

Limitations of the Study

As with any individual piece of research, it's important to interpret these findings with some context in mind.

• The abstract provided does not include full details on sample size, meaning we cannot confirm whether the participant group was large enough to draw broad conclusions.

• The study focused specifically on the bench press, so these findings may not automatically apply to all pressing variations or to other compound movements.

• The populations studied are not described in detail in the available abstract, which makes it difficult to know how applicable the results are to different training ages, experience levels, or athletic backgrounds.

• Resistance training research can sometimes be influenced by how compliance is monitored — whether participants actually adhered strictly to the assigned range of motion throughout the study.

These limitations don't undermine the findings, but they do suggest that further research across different populations and exercises would strengthen the overall picture.

Conclusion

The research suggests that when it comes to the bench press, training through a full range of motion leads to greater neuromuscular adaptations compared to partial range alternatives — at least over a prolonged training period. For most people focused on building strength, this is a useful finding to keep in mind.

Research like this helps inform how coaches structure resistance training programs and reinforces the value of sound, evidence-based technique over shortcuts that may feel productive in the short term. If you're looking to build your training around principles that are grounded in exercise science, connecting with a knowledgeable personal trainer can make a real difference in how you apply findings like these to your own program.
