From unsuccessful workouts to shoddy sleep, there are a handful of sneaky signs you may need a rest day.
For some athletes, the greatest challenge is deciding whether or not to hit the snooze button or go for a run every morning. For some, itâs making the tough call about whether time is better spent doing an interval ride or hitting up happy hour.
But for others â the super ambitious, self-motivated, highly disciplined athletes â the hardest part of training can be knowing when to back off. If youâve been training hard every day, it can be tough to opt for a day off. That can lead to overtraining, injury, or a lack of progress â all of which are mostly avoidable.

âThere are several signs and symptoms of overtraining that both the athlete and coach can look out for,â says Jonathan Cane, exercise physiologist and founder of City Coach Multisport in New York City.
Here are the seven most common signs.
1. Youâre super sore
"Itâs one thing to be sore from adding deadlifts to your routine. Itâs another to face persistent muscle soreness, beyond what would be expected from your recent workouts," says Cane. "If youâre facing lingering, inexplicable aches, itâs best to give yourself a rest day so your muscles can recover appropriately."
2. Your easy workouts feel hard
"Your coach prescribes a track workout every Tuesday â usually 12 x 400 or 8 x 800 â and usually youâre psyched to give it a go."
"But if youâre struggling â physically or mentally â with workouts that would normally be less challenging, it may be time to take a break and regroup," Cane advises.
3. Youâre not hungry
"Normally youâre ravenous, and no post-workout food is safe around you. But if lately your appetite is lacking, that could be a sign that your body needs a break," Cane says.
4. Your heart rate isnât normal
You monitor your heart rate data obsessively (#guilty), so itâs easy to tell when somethingâs up. Maybe youâre unable to get your heart rate significantly elevated even with a high perceived exertion or maybe youâve noticed an elevated resting heart rate.
âA lower heart rate at a given speed or power can be a sign of improved conditioning,â says Cane. âBut usually the rate of perceived exertion is also lower as fitness improves.â
Keep an eye on that ever-important data (thatâs what the Polar Flow app is for!) to make sure your heart is in check â and to keep the rest of your body in check, too.
5. You keep getting sick
The harder the body works, the more susceptible it is to illness. (Blame your potentially weakened immune system.)
If you just canât kick that cold or you find yourself facing infections when youâre normally pretty healthy, see a doctor â and take a day or two off.
6. Youâre not sleeping well
You used to get a solid eight interrupted hours. Now youâre having a hard time falling asleep, or youâre tossing and turning all night. This is probably because your nervous system or your hormones are overloaded.
"Keep an eye on your sleep stats â quantity and quality â to ensure youâre as rested as you need to be to keep performing your best," Cane says.
7. You just donât feel like yourself
Maybe your once-glowing self-esteem is lacking, maybe youâre usually super motivated by now you canât seem to get out the door, or perhaps youâre feeling depressed. All of these are signs you might just need a little time off.
âIf I gave an athlete a rest day every time he or she had one of these symptoms, there wouldnât be much training going on,â says Cane. âBut multiple or repeated signs are probably noteworthy".
Cane says that some athletes benefit from a complete day or two of rest, while others do better with a few active recovery days, or even a week of easy workouts.
âWith time and careful analysis, a smart coach or athlete can identify patterns that lead up to that overtraining â and in the future will help avoid it."
