Brain Endurance Training Study Found Better Gym Performance

A study first published on April 13, 2026, examined whether adding cognitive tasks around physical training could improve gym performance in recreational athletes. Wiley lists the paper in the European Journal of Sport Science. Its findings offer an interesting training question rather than a ready-made prescription.

Yahoo’s October 25 report described better results among participants who combined their gym sessions with brain endurance training, or BET. The reported improvements included more repetitions to failure and better performance on bench press, preacher curl, and jump-squat measures.

For endurance athletes over 35, the useful response is informed curiosity. Before adding another element to an already demanding training schedule, it helps to separate the reported results from the interpretation and then consider their relevance to your goals.

The Reported Gains Came From Gym Performance Tests

According to Yahoo, the BET group increased total repetitions to failure by 50%. The report also described the following improvements in that group:

• 33% in bench press.
• 93% in preacher curl.
• 28% in squat jump.

These are substantial reported changes within a single study. They should stay attached to that study and its particular performance measures rather than becoming predictions for anyone who adds cognitive exercises to training.

Yahoo also reported lower perceived effort among BET participants. The standard-training group showed modest improvements and no significant gains on most of the reported measures.

One distinction matters when reading those percentages: an improvement within one group is not the same as a percentage advantage over another group. The reported increase in total repetitions should not be read as the BET group performing that much better than the standard-training group. Those are different comparisons.

The exercise labels also deserve care. A reported improvement in bench-press performance should not automatically be rewritten as an equivalent increase in maximum strength. Yahoo’s coverage describes repetitions to failure alongside strength and jump measures, so the most faithful wording stays close to those outcomes.

In plain English, the report suggests that participants who completed cognitive tasks around their workouts improved their performance on the study’s gym tests. That is the central finding. It is more specific than a broad claim that training the brain improves every form of athletic performance.

The Comparison Used the Same Physical Training

Yahoo described the research as a randomized study comparing standard gym training with the same exercises paired with cognitive tasks. The intervention ran for 12 sessions. The cognitive tasks occurred before and after the sessions, not while participants performed the physical exercises.

That design is important to the question being tested. According to Yahoo, both groups had identical physical training volume. The added cognitive work was therefore the feature that distinguished the reported training approaches.

Wiley lists the underlying paper as “Remote-Based Brain Endurance Training Enhances Bench Press, Preacher Curl, and Jump Squat Performance in Recreational Athletes.” The title keeps the study’s focus clear: resistance-exercise and jump-squat performance.

The accessible study description leaves several important details unresolved:

• The sample size and sex distribution.
• The participants’ age range.
• The detailed cognitive-task protocol.
• The uncertainty around the reported changes.

Those gaps limit judgments about how dependable the effect was and how closely the participants resembled adults aged 35 to 65. The featured study also did not establish improved running, cycling, triathlon, or other endurance-racing results. Its reported tests addressed a different performance question.

Yahoo reported that the researchers proposed mental resilience as one possible explanation. Their interpretation was that participants may have become better able to push harder or continue longer despite identical physical training volume. That is a proposed explanation for the findings, not a demonstrated account of the mechanism.

Keeping the outcome separate from the explanation allows the result to remain interesting without making it more conclusive than the reporting supports.

For Athletes Over 35, the Training Goal Sets the Standard

For Reendure, translating sports science into useful guidance means considering both immediate performance and the ability to stay active for years. A striking result earns attention, but its relevance to a particular training decision still needs examination.

The practical question is not simply whether BET produced an impressive headline. It is whether the evidence addresses something you are trying to improve and provides enough detail to inform a sensible choice.

Match the Evidence to the Outcome You Value

An endurance athlete may be interested in gym performance for its own sake. In that case, the featured paper offers a relevant research lead. Readers considering their strength work can place it alongside Reendure’s coverage of strength training for runners.

The comparison should begin with the outcome rather than the size of the percentage. Are you assessing repetitions in a gym exercise, performance on a running test, or a result in your chosen event? Naming the goal makes it easier to judge whether a study belongs in the decision.

This is also a useful way to handle competing training ideas. A large reported change in one test does not automatically make an intervention the highest priority for your programme. The evidence needs to address the decision you are actually making.

There is no requirement here to add another task to every session. Keeping BET on a research watchlist is a reasonable response, particularly when the practical details needed to reproduce the intervention remain unresolved.

Preserve the Distinction Between Added Tasks and Multitasking

The timing of the cognitive work is one of the clearest practical details in Yahoo’s account. Any discussion of applying the idea should preserve that before-and-after structure rather than turn it into a claim about doing distracting tasks during exercise.

Adding a mental challenge around a workout and dividing attention during the workout are different proposals. The latter should not be presented as a version of this intervention simply because both involve thinking and exercise.

Nor does the report supply a do-it-yourself programme. Choosing a task, deciding when to use it, and determining its demands would require information beyond the broad description. Personal health or safety questions belong with a qualified clinician rather than a report summary.

For athletes already weighing fatigue or competing demands, it makes sense to consider this idea within the wider question of how a training plan should respond to stress and fatigue. An interesting addition does not have to become an immediate obligation.

The Runner Paper Deserves a Separate Assessment

Wiley also lists a paper titled “Warming Up Body and Mind: Combined Cognitive and Exercise Priming Improves 1-Mile Time Trial Performance in Recreational Runners.” It was first published on April 15, 2026.

That is a more directly relevant research question for runners. However, the accessible listing provides the title and publication information without enough detail to assess the methods, effect size, or limitations. Its wording alone is not sufficient to judge its practical value.

The appropriate next step is to examine that paper’s full methods and results before using it to support a training change. In particular, the intervention and the measured outcome need to be assessed on their own terms.

It would be premature to combine the gym study and the runner paper into a single claim about BET. Cognitive tasks around a training programme and cognitive priming around a performance test should not be assumed to be interchangeable merely because both involve mental and physical activity.

For a curious athlete, this creates a useful distinction between following a research direction and adopting a method. You can take the question seriously while waiting for enough information to evaluate the answer.

The Findings Merit Attention Rather Than a Training Overhaul

The reported BET results are worth following. Yahoo described improved gym performance and lower perceived effort after cognitive tasks were added around otherwise matching physical training.

For endurance athletes over 35, the modest takeaway is to keep the idea in view without treating the reported percentages as personal targets. The evidence does not require a change to training, recovery, or nutrition.

A productive response is to ask for the full intervention details and evidence tied to the outcome that matters to you. Curiosity is justified. An immediate training overhaul is not.
