We’re well aware of the physical benefits exercise offers us. Strength training improves our muscular base, enhances our posture, creates stronger bones, and improves joint health. Cardiovascular training improves our ability to use oxygen effectively, promotes better circulation, and improves our energy levels. Although, what about strength training and brain health? A recent study published discussed the positives resistance training has on brain health.
This study followed 100 subjects, age 55 and over, through a resistance training program that required 80 percent of their peak strength. These 100 subjects were classified to have mild cognitive impairment (MCI) – which is classified as: Noticeable daily mental difficulties, but not large enough difficulties to prevent regular functioning. While further research is needed on this topic, this is one of the first studies to specifically look at heavy resistance training and cognitive benefits.
To give context on MCI, around 80 percent of subjects with positive MCI diagnosis develop Alzheimer’s approximately 6 years after original diagnosis. That’s a scary stat, especially for folks like myself with Alzheimer’s running in their family.

Researchers split the 100 subjects into four groups: resistance training, placebo resistance (stretching), cognitive training, and a placebo equivalent. Resistance training was performed twice a week for 6-months, weights used were increased to 80 percent of subject’s peak strength as muscle increased. They found that the resistance training group had a positive relationship with global cognition. Previous research has found that exercise helps preserve, and enlarge areas of the brain often related to diseases like Alzheimer’s.
This is promising data suggesting the benefit of resistance training and healthy aging of the brain. Researchers also pointed out – to receive the strength training brain benefit – there has to be consistency in training, along with the intensity to match the demands of 80 percent of peak strength.
The Bigger Picture
Yes, this study looked at an older population, but it also gave us valuable insight we can implicate in our training right now. Consistency and progression are key. All of the time you spend training has a pay off; it’s creating a healthier future you. And training goes so much deeper than physical benefits.
1. It creates relationships around you. Your training partners and competitors become a community around you that can offer support.
2. Training creates mental toughness. You learn to set goals, be patient, have discipline, and much more.
3. We learn about ourselves and build self-esteem. When we strength train consistently we’re constantly breaking barriers and reaching new emotional, mental, and physical levels we wouldn’t have found otherwise.
So the next time you’re in the gym – even if your mind isn’t fully there – be grateful for your health and the people around you.
