Exercise and Sleep: When to Train for Better Sleep
Exercise and sleep: when to finish training and caffeine for your bedtime, what to do after a bad night, and where Herbalife drinks fit.
Lose Weight Feel Great | Last updated November 2026
Quick answer: Exercise regularly during the day and finish at least 4 hours before bed, which is the NHS advice for people with insomnia. Stop tea and coffee 6 hours before bed. For a 10:30pm bedtime, that means your workout is done by 6:30pm and your last cuppa is at 4:30pm.
How are exercise and sleep linked?
Exercising regularly during the day is one of the self-help steps for insomnia. It costs nothing and you don't need a gym. A brisk walk counts.
Put your bedtime in the diary, like a gym class.
Adults need 7 to 9 hours of sleep a night. If you're training at 6am on 6 hours of sleep, change your bedtime before you cut the training.

The UK activity guidelines for adults are at least 150 minutes of moderate activity a week, or 75 minutes of vigorous activity. Add strengthening work for all the major muscle groups on at least 2 days.
Moderate means things like brisk walking, riding a bike or dancing. Vigorous means running, swimming or sport such as football or netball.
Spread over a week, 150 minutes is about 21 minutes a day by our sums, so a lunchtime walk covers it.
What time should you stop exercising before bed?
If you struggle to sleep, avoid exercise before bed: finish exercise at least 4 hours before bed and stop tea and coffee 6 hours before.
The NHS Every Mind Matters sleep guide is less strict. It says some people find exercising close to bedtime affects their sleep, and suggests being active earlier in the day. It also suggests putting phones and tablets away for an hour before bed.
Here are those gaps for three bedtimes, worked out by us.
| Bedtime | Last tea or coffee | Exercise done by |
|---|---|---|
| 10pm | 4pm | 6pm |
| 10:30pm | 4:30pm | 6:30pm |
| 11pm | 5pm | 7pm |
Put screens away an hour before whichever bedtime you pick. Use these as targets if you lie awake. If you sleep well after a 7pm class, keep going.

If sleep is a problem, train in the morning or at lunch. That leaves well over 4 hours before bed. If evenings are your only slot, try these three steps.
Move hard sessions earlier for one week
Try morning or lunchtime workouts for a week. Note what time you fall asleep each night, then compare it with a normal week.
Keep late evenings gentle
If the evening is your only free time, keep it gentle and as early as you can, such as a walk straight after dinner rather than a hard circuit at 9pm. If you then lie awake, try a weekend morning instead.
Check the caffeine in pre-workout tablets and tea
Lift Off carries a warning of about 75 mg of caffeine a serving. A serving of Instant Herbal Beverage has 87.5 mg. Have either at 6pm and, by our sums, you'd need a midnight bedtime to keep the 6-hour gap.
Should you exercise after a bad night's sleep?
Our view: swap rather than skip. A walk or some stretching keeps the habit going. Save your hardest session for a day after a good night.
Get up at your normal time. After a bad night, stick to your regular sleeping hours rather than lie in.
Our rule of thumb: if you'd score the night 3 out of 10 or less, make today an easy day.
What is in each Herbalife drink?
Hydrate and Rebuild Strength are for training days. Night Mode is an evening drink, and the tea contains caffeine.
Night Mode
Chamomile and peach flavoured, though chamomile isn't on the ingredient list. Each 6 g scoop gives 28 mg of saffron extract, plus vitamin B6 and riboflavin at 30% of the reference intake each. The label makes no sleep claim.
A 180 g tub gives 30 six-gram scoops by our sums, so about £1.48 a drink. Mix one scoop in about 150 ml of cold or warm water, once a day. It's vegan, and isn't recommended for children or in pregnancy or breastfeeding.
Hydrate
One Hydrate stick goes in 500 ml of water. It has 12 kcal and 0 g sugar, and its magnesium contributes to electrolyte balance and the reduction of tiredness and fatigue.
Rebuild Strength
It's a carbohydrate-protein drink in chocolate flavour, sold here in a 1 kg tub.
Instant Herbal Beverage
It contains caffeine, so have it in the morning or at lunch if you sleep badly. Our Herbalife tea guide covers flavours and prices.
Night Mode: saffron extract, vitamin B6 and riboflavin, one scoop a day, with no caffeine in its ingredients.
Buy Night ModeWhat does an example training week look like?
Here's one for a 10:30pm bedtime. It's an illustration, not a training plan, and it hits 150 moderate minutes and 2 strength days inside the cut-offs.
Monday, Wednesday, Friday and Sunday
30-minute brisk walk at lunchtime. That's 120 minutes.
Tuesday and Thursday
A 20-minute home strength circuit, finished by the table's cut-off. Our beginner home workouts need no kit.
Saturday
A 30-minute bike ride. That takes the week to 150 minutes.
Every evening
Follow the 10:30pm row of the cut-off table, and put your phone away at 9:30pm.
