You’ve crushed yesterday’s workout, but now every movement feels like a battle. Delayed onset muscle soreness (DOMS) has struck. So, should you train with DOMS or take a rest day? Here's the thing: listening to your body is key. But understanding the science behind DOMS can help you make an informed decision.

What Exactly is DOMS?

DOMS is the muscle pain and stiffness that kicks in 12 to 24 hours after a workout, peaking around 48 hours. It’s generally caused by microtears in the muscle fibers from activities like strength training or high-intensity exercises. A study published in the Journal of Athletic Training around 2017 noted that eccentric exercises—those where muscles lengthen under tension—are a common cause.

Should You Workout with DOMS?

Let's bust a myth: working out with DOMS doesn't automatically lead to more gains. Some believe that pushing through the pain will speed up recovery or increase muscle growth. However, training with severe DOMS can actually impair muscle function and increase the risk of injury.

In my years of coaching, I had a client who decided to push through their DOMS with heavy squats and ended up with a knee strain. It set them back weeks in their training. Instead, consider active recovery like light exercises or stretching to promote blood flow and reduce soreness.

When to Rest vs. When to Push Through

Here are some guidelines to help you decide:

  • Mild Soreness: If it's just a bit of soreness, you can generally push through with a lighter workout or focus on different muscle groups.
  • Severe Pain: If your muscles feel very tender or you’re experiencing swelling, it's best to rest or engage in light activity.
  • Persistent Soreness: If DOMS doesn't improve after several days, consult a healthcare provider. It could indicate an injury.

How to Prevent Severe DOMS

Prevention is better than cure. Gradual progression in intensity can help minimize DOMS. Incorporate a proper warm-up routine before intense workouts. Also, consider adding more foam rolling and dynamic stretching into your routine.

Even your nutrition plays a role. A diet rich in protein can help repair and build the muscle fibers affected by exercise. Check out our high-protein foods guide for ideas.

In the end, the goal is to maintain a balance. Training consistently is important, but knowing when to rest is equally crucial for progress. Next time you're faced with DOMS, assess your soreness and remember that it's okay to take a break. Rest up, recover well, and return to the gym stronger.
