Strength training is neurological prevention. An MRI study presented today at the RSNA Congress in Chicago shows that those who build muscle and reduce visceral fat measurably slow down brain aging. At the same time, current research results from Australia provide concrete approaches to performance optimization – while a fundamental change is taking place in training practice.
The times when building muscle was primarily for aesthetic purposes are over. The latest scientific data paints a picture of “neuroprotective fitness”. The focus is on a large-scale study that quantifies for the first time how the ratio of visceral fat to muscle mass determines the biological age of our brain.
The Washington University School of Medicine research team at Dr. Cyrus Raji examined 1,164 healthy adults using whole-body MRI and artificial intelligence. The result is clear: a higher proportion of muscle combined with low visceral fat correlates significantly with a younger biological brain age.

“Healthier bodies with more muscle mass and less hidden belly fat are more likely to have healthier, more youthful brains,” explains Dr. Raji. The study differentiates sharply between subcutaneous fat under the skin and visceral fat between organs. While subcutaneous fat did not show a significant effect, visceral fat was found to accelerate brain aging.
The Implication: Building muscle is active brain care. Dr. Raji emphasizes that muscle mass can serve as an intervention marker that reduces frailty while lowering the risk of Alzheimer’s disease. Strength training increases from the metabolic to the neurological level.

Die Edith Cowan University in Perth simultaneously provides precise data for training practice. A meta-analysis at Dr. Cody Wilson quantifies the effect of muscle temperature on performance: for every increase of 1°C, performance increases by an average 3.5 percent.
This effect is particularly significant with fast-moving movements and explosive strength, but less so with pure maximum strength. Surprising: The heating method is secondary. “Both active warm-ups and passive methods such as heat pads or hot showers result in improved speed and strength,” says Wilson.
Professor Tony Blazevich adds: “Once you’re sweating lightly, you’ve probably raised your temperature sufficiently. The most important thing is to start.” For those who save time, this means: Passive heat supply before training already delivers physiological benefits.
Deep Core statt Sixpack-Crunches
At the same time, a paradigm shift is taking place in training practice. Leading trainers are moving away from isolated crunches and focusing on the deep core muscles – the Transversus abdominis muscle.
Current recommendations emphasize “anti-rotation” and “anti-flexion” exercises. Certified trainer Melissa Kendter recommends using mini bands and light dumbbells to activate deep stabilizers instead of just training the superficial abdominal muscles.
A Pilates adaptation is becoming established, particularly for the 50+ generation: controlled exercises such as “toe taps” or the “spine twist” replace risky, dynamic movements. This approach correlates directly with the RSNA results – it is about maintaining functionality and reducing visceral fat through constant, controlled muscle work.
The GLP-1 challenge
The findings coincide with a pharmaceutical revolution: the widespread use of GLP-1 agonists such as Ozempic or Wegovy for weight loss. While these medications are effective at reducing fat, they often result in significant muscle loss.
The RSNA study offers a critical warning: “If we lose fat – particularly visceral fat – but lose muscle, the neuroprotective effect could be diminished.”
This creates new urgency for accompanying strength training. Physicians and trainers need to work more closely together to ensure that patients receiving drug therapy for obesity undergo mandatory hypertrophy training. The goal shifts from “weight loss” to “re-composition” as a preventive measure against Alzheimer’s and dementia.
What changes now
Based on the current data, clear developments are emerging:
Diagnostics-based training: The ratio of visceral fat to muscle mass is becoming the new key metric for personal trainers and health centers – beyond BMI.
Thermo-Training: Gyms could increasingly offer warming cabins or heated training areas to integrate passive warm-up into the training process.
Equipment minimalism: The trend towards deep core training with minimal equipment lowers the barrier to entry while at the same time providing high functional returns.
The bottom line: Muscles are the most important organ for longevity. Anyone who lifts weights today is investing directly in the future of their brain.
