Why Am I More Sore Two Days After Exercising?

Why Am I More Sore Two Days After Exercising? A Physical Therapist Answers

By Nova Physical Therapy | North Hollywood, CA

Patient Question

"Why do I feel more sore one or two days after exercising instead of right away, and can physical therapy help?"

The Short Answer

Feeling sore one or two days after exercise is a common experience, especially after starting a new activity, increasing exercise intensity, or performing unfamiliar movements. This temporary soreness is commonly referred to as delayed onset muscle soreness (DOMS).

Research suggests that delayed muscle soreness is associated with the body's normal response to unaccustomed or higher-intensity physical activity. A licensed physical therapist can evaluate movement patterns, strength, flexibility, and exercise tolerance to help determine whether your symptoms are consistent with expected post-exercise soreness or whether additional evaluation may be appropriate.

Why Does Muscle Soreness Peak After One or Two Days?

Unlike a bruise or cut, muscle soreness after exercise often develops gradually.

Many individuals notice:

• Little or no soreness immediately after exercise
• Increased soreness the following day
• Peak soreness between 24 and 72 hours
• Gradual improvement over the next several days

The exact timeline varies depending on the individual, the type of activity performed, and the body's response to exercise.

Why Does This Happen?

Exercise places demands on muscles that encourage the body to adapt over time.

Several factors may contribute to delayed soreness, including:

• Performing unfamiliar exercises
• Increasing exercise intensity
• Returning to exercise after a break
• Resistance training
• Hiking or downhill walking
• Sports participation
• Higher training volumes

Research suggests that delayed soreness is related to the body's normal adaptation process following physical activity rather than the buildup of lactic acid, which clears from the body relatively quickly after exercise.

Is Muscle Soreness a Good Sign?

Muscle soreness does not necessarily determine whether an exercise session was effective.

Some productive workouts cause little soreness, while others may produce more noticeable discomfort.

Progress is generally influenced by consistent participation in an appropriately designed exercise program rather than how sore you feel afterward.

When Is Soreness Different From Pain?

Although temporary muscle soreness is common, symptoms may warrant further evaluation if they include:

• Sharp pain during activity
• Significant swelling
• Joint instability
• Inability to bear weight
• Loss of function
• Symptoms that continue worsening instead of improving

A physical therapist can help determine whether your symptoms are consistent with expected exercise responses or whether additional evaluation may be appropriate.

Can Physical Therapy Help?

Physical therapists help individuals safely participate in physical activity while improving movement quality and reducing the risk of overloading tissues.

Depending on examination findings, treatment may include:

• Therapeutic exercise
• Progressive strengthening programs
• Flexibility exercises
• Mobility training
• Functional movement training
• Balance exercises
• Activity modification education
• Recovery education
• Home exercise programs
• Return-to-sport progression

Physical therapy focuses on improving movement, restoring function, increasing activity tolerance, and helping individuals safely reach their activity goals.

What Does Research Say?

Research supports progressive exercise programs as an effective strategy for improving strength, physical function, and overall health.

Studies also suggest that gradual progression of exercise volume and intensity may help the body adapt while reducing excessive post-exercise soreness.

The American College of Sports Medicine and the World Health Organization recommend regular physical activity as part of a healthy lifestyle.

Frequently Asked Questions

Is soreness caused by lactic acid?

Current research indicates that delayed muscle soreness is not caused by lactic acid. Lactic acid is cleared from the body relatively soon after exercise.

Should I exercise if I'm sore?

Activity recommendations should be individualized. Light movement may be appropriate for some individuals, while others may benefit from additional recovery depending on the intensity of soreness and their overall health.

Will I always get sore after exercising?

Many people notice that soreness decreases over time as their body gradually adapts to regular physical activity.

Can physical therapy help me return to exercise safely?

Yes. A physical therapist can evaluate your movement, functional capacity, and exercise tolerance to develop an individualized program that matches your goals and current abilities.
