If you’ve ever felt muscle pains a day or two after an intense workout, the kind that limits your flexibility and makes sitting down (after a leg day) or raising your arms (after an upper-body day) difficult, you’ve experienced DOMS firsthand. 

DOMS stands for ‘delayed onset muscle soreness’ and typically peaks about 24-72 hours after a workout. DOMS is most often triggered by high-intensity workouts, especially those that include a lot of eccentric (decelerating) movements. These exercises often lead to microscopic tears in muscle fibers, which bring about inflammation in the affected areas and cause feelings of soreness.

If you are unsure, an example of an eccentric movement is the downward motion in a Romanian deadlift (where the hamstrings are extended), or the downward motion of your forearms after a bicep curl.

Note, however, that delayed onset muscle soreness cannot be felt during a workout. If your muscles feel tired while exercising, you’re experiencing what is called acute muscle soreness. This kind of soreness should disappear shortly after you are done with your workout, while DOMS will likely kick in about 12-24 hours after your workout (hence the “delayed onset” part of the name!)

Signs and Symptoms of DOMS

Delayed onset muscle soreness (DOMS) is a perfectly normal response of the body to strenuous exercise, and typically is nothing to worry about. If anything, it is a bit inconvenient and sometimes painful, but can be managed quite well (read on to find out some ways to treat DOMS and reduce pain).

Common symptoms of DOMS include:

  • Reduced range of motion (because the sore muscles can’t move adjacent joints properly while affected by DOMS)
  • Stiffness and difficulty stretching the affected muscles
  • Muscles feel tender
  • Muscle fatigue and a temporary decrease in strength

Who can get DOMS?

DOMS can affect anyone, from the brand new gym-goer to pro athlete. Muscle soreness most often occurs after you introduce new exercises, start a new exercise routine, increase exercise intensity, or introduce more eccentric movements (muscle extensions). While uncomfortable, DOMS is considered to be part of the body’s normal response to increased exercise intensity and is part of the adaptation process during which the body learns to tolerate these kinds of workouts.

Is DOMS a sign of a good workout?

It’s a common misconception to think that in order to have had a good workout, one must have gotten very sore from it. 

This idea is based on the premise that the micro-tears in muscle fibers that make you sore are a step toward muscle growth or hypertrophy. 

But primarily, delayed onset muscle soreness is just an indicator that you performed a more difficult workout than what your body was accustomed to. As you perform more comparable workouts, DOMS will become less likely, but you’ll still have worked hard and have gotten in a good exercise session. 

In my humble opinion as a personal trainer, consistency trumps doing random and rare high-intensity workouts. Your chances to reach your fitness goals are much better if you perform sustainable workouts consistently (that won’t always make you sore) compared to performing one “extreme” bout of exercise per week that leaves you debilitated and unable to work out again until the following week.

How to treat DOMS

In the vast majority of cases, DOMS will disappear on its own, usually about two to three days after you started feeling sore. But, as you’ll likely know, it’s not a very comfortable feeling. The below-listed methods can help alleviate muscle pain and make your life a bit easier while dealing with delayed onset muscle soreness (DOMS). 

Staying active

When you’re extra sore, your first instinct might be to rest as much as possible and just not move until the soreness subsides… right? 

Contrary to this intuition, it’s not the best idea to stop moving altogether when sore. In fact, remaining active, doing some light exercise, and following an active recovery routine can help treat DOMS better than anything else, and make it go away faster than rest alone. 

If you’re intrigued by this and would like to learn more about why active recovery tends to be better than pure rest, read our post on active recovery

Definitely take a break from highly strenuous exercise within the same muscle group to give your body a chance to rest and recover, and reduce the risk of further injury. 

Massage guns

Five years ago, the go-to answer to “How to treat DOMS” would have been foam rollers. But with time, the fitness and recovery world has produced a much more effective tool for reducing muscle soreness and restoring range of motion in sore muscles: hand-held massage guns. Due to their ability to penetrate muscle tissues much more deeply than foam rollers, they have the ability to release muscle knots and relieve discomfort caused by DOMS. Percussion therapy (as provided by massage guns) increases blood flow to the affected muscles which helps them recover faster. 

This review of several studies on the effects of post-workout massages shows that participants reported significant decreases in muscle soreness if they received a massage 24, 48, and/or 72 hours after exercising than those who did not.

Because it can get pricey and pretty inconvenient to get a professional massage after every workout, we love massage guns that can be used to self-massage at any time, and everywhere.

Heat and ice therapy

Coldwater immersion (or a cold bath) is a popular method used by athletes to treat lactic acid buildup and DOMS post-workout. While not perfectly conclusive, some studies do suggest that cold water immersion (or an ice bath) is effective in reducing DOMS1. While providing a very different level of enjoyment (you know what I mean if you’ve ever taken an ice bath!) heat therapy (such as via a warm bath or heat compressions) is also an effective method2 in decreasing stiffness and DOMS.

Can you prevent DOMS?

Not really, but you might be able to keep its intensity at bay by:

  • Limiting your exercises to concentric and isometric movements and contractions (aka limiting eccentric movements – this shouldn’t be your primary long-term tactic because eccentric movements are important to be implemented in your routine. But if you want to avoid DOMS on one day specifically, you can do this!)
  • Training with a certified personal trainer to safely progress your workouts. 
  • Following a training split and not working the same muscle groups two days in a row – this gives your body time to deal with delayed onset muscle soreness without adding to it.
  • Making sure to always warm up your body to prevent stiffness and reduce the risk of injuries.
