Do You Really Need to Add Rest Days Into Your Exercise Routine?

Rest days are a standard part of exercise programs, but they’re not the only way to avoid overworking yourself. Contrary to what a lot of beginner advice says, you don't always need a rest day after each day of exercise, and you can even work out seven days a week if you like. But once you start bending the rules, you'll need to take some extra effort to make sure you allow yourself enough recovery, even if it doesn't come in the form of rest.

Recovery is important (whether it comes in the form of "rest days" or not)

Most strength training programs either work your whole body and then have you rest the next day, or else they have you split up your workouts so that each muscle group gets a day of rest—for example, your arms get a rest on leg day. The idea is to let each muscle recover from a workout before you ask it to do the same thing again, and rest days are a valid way of making sure you're getting some time to recover.

But not every activity works this way. Runners, for example, often run every day, and may only take one or two true rest days a week (or, for some, zero). But within that pattern, they will alternate days of hard running (like speedwork, hill running, or long runs) with easy runs that feel less challenging to the body. The easy run days may not be "rest," but they do count as recovery time for an experienced runner.

Other sports may fall somewhere in between, but nobody expects to work every body part to exhaustion every day. Even when elite athletes do workouts every day that look killer to us, it’s because our “hard” is their “easy”. You can bet their coaches schedule in enough of the easier workouts to keep the athlete’s progress on track with minimal risk of injury.

Whatever your schedule looks like, those rest days or easy days are there to help us pace ourselves. Too much hard running, if you’re not used to it, sets you up for tendonitis and other overuse injuries. And too much exercise of any kind can lead to a syndrome called overtraining where your body may develop flu-like symptoms and disturbed sleep because it just can’t keep up with the demands you’re putting on it.

There’s Nothing Magic About Resting for One Day

Taking a single rest day after a hard workout isn’t the only way to keep yourself from overtraining. There are a few reasons it’s a good rule of thumb, though:

• Resting every other day means only half of your days will be hard workouts. The other half will be rest days or easier days, so the schedule keeps your total workout intensity manageable.

• An alternating schedule is easy to follow. You don't have to ask yourself whether your recovery work is easy enough, or memorize which exercises work which muscles. You just stay home if it's not a workout day, and you know you're on track.

• Mentally, it’s easier to stick to a workout when you enjoy it. Hard workouts aren’t always fun, and you may need to psych yourself up to try something really challenging. It’s okay if you don’t feel up to that every day. Having some easier, more relaxing days can help you stick to your schedule.

• Routines with rest days are easier to schedule around your life. People who work out six days a week have to fit those workouts around everything that's going on in their lives. Having multiple rest days every week means you have more time for work, school, family, hobbies, and anything else that competes for those time slots.

If you can accomplish those goals with another schedule, though, feel free to do so. If you enjoy all your workouts, even the hard ones, slowly include more hard days in your schedule. If you feel okay with that, keep doing it! But if you end up sore or fatigued, listen to your body and put those rest days back in.

Recovery Doesn’t Have to Mean Total Rest

Some people prefer the term “recovery” to “rest” days, because total rest isn’t necessarily your goal. After all, lifting a fork to your mouth is a similar action to a bicep curl, so if you just did a heavy arm day, would you be unable to eat? Clearly, some amount of activity is fine on a rest or recovery day.

This is where you have to calibrate your own sense of effort. If you’re new to exercising and you just did a day of heavy squats, a five mile bike ride is probably not a great choice for the following day. But if you bike five miles to work every day, you should be able to keep doing that even on your “rest” days.

When I did push-ups every day for 30 days, a few people suggested that I was setting myself up for injury by not taking rest days. But as I wrote in that article, I ramped up my fitness very carefully. A few sets of pushups every day became my new normal, and it was no more taxing to me than a bike ride is to a bike commuter. Some days I would try a more challenging type of pushup or I might do more reps than usual; but I balanced out those harder days with, you guessed it, easier days that are closer to my baseline effort level.

As you learn your own strengths and limitations, you too can alter your workout schedule according to what works for you. That might mean you only take one or two rest days per week, or it might mean you do mega-hard workouts and then lay low for a few days. If you’re getting a reasonable amount of exercise in total, and if you aren’t getting sore or injured, you’re probably doing okay. Now, let me ask some of the specific questions that I know tend to come up in these discussions?

Can I walk or do cardio on rest days?

Yes, if that's your baseline level of activity. If you always go for a walk after dinner, there's no need to skip that just because it's a rest day. If you want to start adding cardio on your rest days, make sure you're recovering well from whatever you're already doing. Feel free to add in that extra cardio, or other easy movement, a little bit at a time. I also have this guide to figuring out what to do on your rest days.

How do I know when I need a rest day?

If you can't tell the difference between feeling lazy and needing a rest day, ask yourself: Do I want to skip my workout or do I need to skip my workout? If you feel like you need a rest day, you probably do. It's OK to take a rest day if you feel sick, or if you're unusually tired or busy. A workout is just a workout. It can wait.

If you ask yourself this question and decide you just don't want to work out, consider moving the workout to another day or time. Or, if there's really no reason to skip, go do the workout anyway. Any time I feel this way, I always feel better afterward, and I'm glad I got the workout done.

But if you're asking yourself this question pretty often, you should probably revisit your workout routine and make sure it's actually working for you. Rest (or recovery) days should be preventative. They keep you from getting too run-down.

Do I need rest days if I'm not sore?

Soreness doesn't have much to do with recovery, believe it or not. You can be well-recovered but feeling a little sore, or vice versa. On a new exercise program, I'd advise sticking to your scheduled recovery days. After two weeks, that's when you can add in some extra work on those recovery days as long as you're still feeling good.

What happens if I don't take my rest day?

You might feel a little more fatigued for your next workout. Over time, if you don't take any rest days, you may find you're lifting less weight or performing poorly in workouts. You may notice other effects on your health, like poor sleep.

But then again, maybe you'll be fine. As we discussed above, rest days aren't magic, they're just a tool in the toolbox. If you work out every day, but your total amount of work is within your body's limits, you might recover just fine and this becomes your new normal. Pay attention to how you're feeling, though, and add those rest days back in if you feel you need them.
