Resistance training makes us happier and smarter
A new study shows that lifting weights impacts not only the body but also sleep, mood, cognition, and daily functioning.
Introduction
A clinical trial conducted on a group of older women found that regular resistance training improves far more than physical strength and appearance. After just 12 weeks, participants reported better mental health, sharper cognitive performance, and deeper, more restorative sleep. They became happier, calmer, and more capable in everyday life.
Key findings
Researchers confirmed that resistance training is a powerful tool to support the mind, brain, and functional capacity — even later in life.
Better mood
Depression and anxiety scores dropped significantly — participants felt happier.
Sharper mind
Memory, attention, verbal fluency, and reaction time all improved — training made them smarter.
Improved sleep
The average PSQI score fell from 7.26 to 4.61, showing deeper and calmer sleep.
Functional independence
More strength, better results in walking and chair-stand tests — easier daily functioning.
