Does it matter what time you train?
By Matheus de Paiva, Exercise coach, BSc Physical Therapy, MSc Rehabilitation Science. Updated 2026-10-03.
In a 12-week University of Basel trial, 108 adults aged 60 to 80 trained either at the hour they were personally strongest or at their weakest. The peak-time group gained no more strength or lean mass. Even an 11% daily swing in strength changed nothing. The best hour to train is the one you will keep.
Who this guide is for
- Adults 60+
- Strength training
- Busy schedules
What the study found
Researchers at the University of Basel randomly assigned 108 adults aged 60 to 80 to train for twelve weeks either at their personal daily peak or at their daily low point.
The peak-time group gained no more strength or lean muscle than the trough-time group, even though daily strength swung by about 11% on average between the two hours.
Why the hour does not decide the result
Muscles adapt to the work you do over weeks and months, not to the hour on the clock. Consistency and gradual progression drive the gains.
Feeling stronger at a certain hour is real, but in this trial it did not translate into better results. Showing up regularly beat showing up at the perfect time.
How to pick your training hour
- Choose the time you can repeat most days. A 7 AM session you actually do beats a 5 PM session you keep skipping.
- Train when your energy and pain are usually at their best, not when a chart says you peak.
- Keep the hour roughly consistent. A regular slot becomes a habit faster than a floating one.
- If your schedule changes, move the session rather than skipping it. The hour matters far less than the week.
- Give a new time slot two weeks before judging it. The first few sessions at an unusual hour always feel off.
When to check with a health professional
- Chest pain, unusual shortness of breath or dizziness during exercise
- A new injury or surgery before restarting training
- You take medication that affects heart rate or blood pressure and want guidance on intensity
Common questions
Should I train in the morning or evening?
Whichever you will do consistently. The Basel trial found no difference in strength or muscle gains between personal peak and low hours in adults 60 to 80.
But I feel weaker in the morning. Does that matter?
The feeling is real, but it did not change the results over twelve weeks. Warm up a little longer at hours when you feel sluggish.
Does this apply to younger people too?
This trial studied adults 60 to 80. Other research in younger adults is mixed, but the practical advice holds: the best time is the one that fits your life.
What if I can only train late at night?
Then train late at night. Keep the sessions a bit lighter if sleep is an issue, and protect your wind-down time after.
