The Role of Deadlifts and Exercise in Brain Health
With the increasing cases of Alzheimer’s and other forms of dementia, many individuals seek ways to maintain their brain health as they age. Neurophysiologist Louisa Nicola highlights a physical exercise that stands out for brain health.
The Power of the Deadlift
On a recent episode of The Diary of a CEO podcast, Louisa Nicola emphasized the deadlift’s benefits. She suggests that this exercise engages nearly the entire body.
If done correctly, the deadlift can use almost every muscle in your body,” she noted. Nicola mentioned muscles like the erector spinae, glutes, quadriceps, serratus anterior, and calves. Her view is that activating numerous muscle groups simultaneously is comparable to a barbell squat.
Nicola also advocates for lifting heavier weights as it demands more of the brain. She likens the brain to real estate that benefits from heavy lifting. Heavier loads require increased neural resources, resulting in a greater “neural drive,” which she believes supports cognitive health.
Dementia and the Broader Context
The discussion takes place amid rising global concerns over dementia. According to the Alzheimer’s Association, Alzheimer’s disease accounts for 60 to 80 percent of dementia cases. As experts look for treatments, physical activity has gained recognition for its role in healthy aging and reducing dementia risk.
Nuances in Exercise and Brain Health
Experts emphasized that while the deadlift is beneficial, no single exercise can prevent Alzheimer’s disease. Dr. Joanna Fong-Isariyawongse points to research indicating that various exercises support different brain health aspects. Resistance training aids overall cognition, while aerobic activities enhance memory. Balance-focused exercises are also effective in older adults.
Rather than one single exercise, a combination tends to offer the broadest protection,” Fong-Isariyawongse explained.
Dr. Sergio Guiteau discussed the lack of direct evidence linking heavier weightlifting to neuroprotection. He stressed that activities challenging balance, coordination, and learning decrease dementia risk more than simply maxing out weight on a deadlift.
Dr. Parth Bhavsar highlighted that consistent and safe exercises contribute to long-term brain health. Factors beyond lifting heavy weights, such as cardiovascular fitness and proper technique, are essential.
Alternative Exercises for Brain Benefits
Experts noted that heavy deadlifts are not required for brain benefits. Machine weights, resistance bands, bodyweight exercises, walking, and tai chi offer significant brain health advantages with lower injury risks.
The encouraging part is that none of this requires deadlifting heavy,” Fong-Isariyawongse said.
Bhavsar listed alternatives like trap-bar deadlifts, kettlebell deadlifts, and sit-to-stand exercises. Dr. Mariam Zakhary also suggested chair squats, resistance-band exercises, and supervised machine-based training as effective options. These exercises recruit multiple muscle groups and challenge coordination and balance.
The Consistency Factor in Brain Health
Experts agree that consistency is crucial for brain health through exercise. Bhavsar pointed to the 2024 Lancet commission report identifying physical inactivity as a modifiable dementia risk factor. Regular physical activity, as recommended by the CDC and WHO, helps reduce cognitive decline risk.
The most beneficial form of exercise will be the one that safely challenges both your cardiovascular system and your musculoskeletal system and allows you to sustain the exercise over time,” Zakhary noted.
Alongside physical activity, learning new skills or languages can also enhance brain connectivity. Experts suggest a diverse exercise routine rather than focusing on a single movement like the deadlift for optimal brain health.
