We spend a lot of time encouraging you to work up a sweat to help you get — and stay — fit. So if we’re recommending you take a day to do pretty much nothing, well, there’s probably a good reason.
Rest days are crucial not just for giving your body time to recover from workouts, but also to help your muscles become stronger and bigger as they rebuild. (Before we start, make sure you’re well-versed in the difference between rest days and recovery days.)
You hear elite athletes talk about taking rest days and recovery days, but a rest day is important even if you don’t consider yourself an athlete. So if you just started the 21 Day Fix and are new to the stimuli and physical stress of working out, or if you’ve been working to your maximum capacity with INSANITY MAX:30 every day, you want to make sure to give your body a break from time to time.
“Heavy exercise designed to elicit maximum gains in strength and power damage muscle to an extent,” explains Elaine Choung-Hee Lee, Ph.D., associate director of the Human Performance Laboratory at the University of Connecticut. “Day after day with little time between heavy training sessions, muscle may not have time to fully recover, and you’ll actually see a decrease in strength, power, and endurance.”
On The Cellular Level
Working out causes microscopic tears in muscle tissue. As your body repairs the damage, it remodels your muscles into larger, stronger versions of themselves so that they’re better able to handle the stresses and strains of working out next time. This process also entails a certain amount of inflammation, which can take up to three days to resolve, says Lee.
In addition to the physical effects, intense workouts can also tax the nervous system, says Mike Bracko, C.S.C.S., exercise physiologist and fellow in the American College of Sports Medicine (ACSM). “On a recovery day, the sympathetic nervous system (the ‘fight-or-flight’ response) is decreased and the parasympathetic (calming) nervous system is stimulated. This allows the body to rest and relax, cortisol levels to decrease, muscles to rest and rebuild stronger, and carbohydrate stores to be replenished,” Bracko explains.
You should take at least one day off per week, though the ACSM recommends beginners give themselves a rest day in between workouts. Additionally, if you’re completely gassed from training hard, take that as a cue to take a full day off and not exert effort to do much of anything, Bracko says.
OK, so now that you understand why it’s okay to give yourself a day off, what is the best way to take a rest day? We’ve outlined it below.
4 Things You Should Do for An Effective Rest Day
“Sleeping is hands down the most important part of any fitness program,” Bracko says. Scoring quality shut eye both when training and resting is crucial. The whole point of a rest day is you’re giving your body the opportunity to recuperate, and nothing helps decrease the strain on your systems like loading up on sleep. Shoot for at least eight hours.
Eat the Rainbow
A rest day means you’re giving yourself a day off from training — not a day off from your diet. It’s always important to ensure you’re getting enough macronutrients (carbohydrates, fats, and proteins). But the other nutrients that fresh food offers are important too as Lee says those training days tap into your key nutrient stores. “Antioxidant-rich, micronutrient-rich, and vitamin-rich foods are especially important to recovering muscle tissue,” says Lee. So put down those fries.
Instead, eat fruits and vegetables in a rainbow of colors — the hues are often evidence of a specific micronutrient, so you want to eat as many as possible — as well as healthy fats, like avocado, olive oil, salmon, or a supplement like omega-3 fatty acids, all of which can help combat inflammation.
Don’t Skimp on Protein
You’ve probably heard it’s important to consume protein within 30 minutes after a grueling workout, but studies show that your body’s ability to utilize protein to build muscle remains elevated for a full 24 hours after your sweat session. Your day off is likely still within that post-workout 24-hour window, so your body is still working to rebuild torn muscle tissue even if you aren’t causing any new damage that day. To do this, your body needs a fully-stocked amino acid pool from proteins — so eat up that protein!
Powders like Beachbody Performance Recover post workout formula will deliver 20 grams of protein along with nutrients like pomegranate extract to help promote muscle recovery and reduce muscle soreness.
Think of it this way: Downing sufficient protein every day gives your muscles the best chance to rebuild as strong as they possibly can after a single workout. What better argument is there?
“Drinking water to maintain a hydrated state during training, after exercise, and during recovery is critical to not only performance but also to reducing fatigue, improving your mood, and improving cognitive function,” Lee explains. When you’re properly hydrated, your body is functioning as optimally as possible.
How much water should you guzzle? “Drink so that when you pee, your urine is the color of light lemonade,” Lee offers.
Rest Day vs. Recovery Day
If you’re feeling completely wiped from a tough workout, don’t hesitate to kick your heels up and give yourself a day of complete rest. “Fully passive rest days are important for replenishing nutrient stores,” Lee says.
But if you’re feeling good, or just a little sore, consider performing “recovery activities” like walking, easy cycling, swimming, or yoga, along with foam rolling the muscles, all of which which will boost blood flow to your muscles, enhancing the delivery nutrients that facilitate their repair and growth, and eliminating substances that hinder them.
