Just 11 minutes of daily exercise could strengthen muscles, study suggests

First seen Jul 09, 2026 · Last updated Jul 10, 2026 · Updated 1 time
Summary
This study investigates whether brief, frequent exercise sessions—called 'exercise snacks'—can improve muscle strength in sedentary young women aged 18 to 25. Participants are assigned to either an exercise snacks group (short bouts of activity spread throughout the day, totaling about 75 minutes per week), a regular exercise group (longer sessions three times per week), or a control group that maintains their usual routine. The trial measures changes in muscle strength and physical fitness after 8 weeks to see if the snack-sized approach is effective and practical.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- exercise snacks (short bouts of physical activity distributed across the day)
- What this could lead to
- If effective, exercise snacks could offer a time-efficient way for sedentary people to improve muscle strength without long gym sessions.
- What could go wrong
- This is a small, early-stage study in a specific group (sedentary female university students), so results may not apply to others. The intervention is short (8 weeks), and long-term benefits are unknown.
