You can, but you probably shouldn't push hard. A gentle walk or a light session is fine if you feel up to it. A heavy lift or a brutal run with a pounding head and a rolling stomach is a bad idea. Your body spent the night processing beer. Don't ask it to also set personal records.
For the bigger picture, read does alcohol stop weight loss.
Is it safe to exercise hungover?
Light exercise is usually fine. Heavy exercise while dehydrated, dizzy and nauseous is a recipe for a bad time. If you feel faint, have a racing heart or are throwing up, skip it. Rest and fluids are the move. If you feel okay, a walk and some fresh air can help.
Common sense applies. If you wouldn't drive, you probably shouldn't deadlift.
What actually helps a hangover?
Not much magic exists, but a few things help:
- Water. You are dehydrated.
- A real meal with protein and carbs. Eggs and toast beat a fry-up of regret.
- Sleep. If you can nap, nap.
- Gentle movement. A walk helps some men feel human again.
Skip "hair of the dog." That is how Saturday becomes a lifestyle.
How does alcohol affect your training?
A 2025 review in Sleep Medicine Reviews found that alcohol reduces REM sleep in a dose-dependent way, even at around two standard drinks. That means worse recovery and groggier sessions. A 2014 study also found that heavy drinking after a hard workout, about 12 standard drinks, cut muscle protein building by 24%.
That was a big night, not a casual pint, but you get the idea. Heavy drinking and training don't mix well.
What should you do if you drank last night?
- Drink water first, and keep sipping.
- Eat something with protein and carbs.
- Decide based on how you feel. Fine? Do a light session. Awful? Walk or rest.
- Lower the weights and the ambition.
- Go to bed early tonight.
If you skip the gym, don't spiral. One missed session doesn't wreck anything. Never miss twice. Read fell off the fitness wagon.
What about drinking and fat loss?
Drinks add calories, and drinking tends to bring food with it. A review of 22 studies found that people who drank ate more food and took in more total calories, and none ate less to make up for it. So Saturday's hangover burger isn't a coincidence. Read how to lose a beer belly.
How do you drink and still train?
Set limits. Drink on fewer days, pick lighter options, alternate with water and eat first. Plan your training for the days when you are not hungover. Most men can have both a social life and a body they like, with a bit of arithmetic.
The Dietary Guidelines for Americans 2025 to 2030 simply advise to consume less alcohol for better overall health. Less is better.
When is a hangover a problem?
If you drink heavily and often, or can't cut back, talk to your doctor. That is a health question, not a fitness one.
The bottom line
Hungover? Walk, hydrate, eat and go easy. Save the heavy lifting for a day your body is on your side. Start the restart plan and plan the week around your life.
Drink water, FATBOY.
