Muscle Strains Explained
Why Sitting Still Won’t Heal Your Muscle Strain (And What Will)
Muscle strains can strike anyone—whether you’re crushing a WOD, chasing your kids around the park, or just bending the wrong way. The instinct? Rest. But here’s the truth: doing nothing can actually slow your recovery. The real secret to bouncing back? Smart movement, progressive loading, and rebuilding strength, so your muscles come back stronger, not just less sore.
One of the most common misconceptions we hear at OMNI Sport Performance & Physical Therapy is that rest is the best solution. While rest has its place, it’s far from the full answer. Recovery is about restoring strength, mobility, and confidence—not just waiting it out.
What Is a Muscle Strain?
A muscle strain happens when muscle fibers are overstretched or torn—often from sudden force, overuse, or poor loading mechanics. Strains are categorized into three grades based on severity, and each requires a different recovery approach.
The 3 Grades of Muscle Strains

Grade I: Mild Strain
-
What it feels like: Mild soreness or tightness without major strength loss.
-
Healing timeline: ~1–3 weeks.
-
PT focus: Keep you moving with mobility and light loading.
Interventions may include:
-
Soft tissue mobilization
-
Isometric exercises
-
Gentle mobility drills
-
Gradual strengthening
Grade II: Moderate Strain
-
What it feels like: Noticeable pain, swelling, bruising, and reduced ROM/strength.
-
Healing timeline: ~4–8 weeks.
-
PT focus: Restore movement quality, rebuild strength, and prevent compensation.
Interventions may include:
-
Controlled mobility and stretching
-
Neuromuscular re-education
-
Strength progression (tempo, eccentrics)
-
Sport-specific retraining
Grade III: Severe Strain / Complete Tear
-
What it feels like: Sharp pain, bruising, deformity, and major loss of function.
-
Healing timeline: 8–12+ weeks (surgery may be needed).
-
PT focus: Post-surgical recovery, restore baseline function, and carefully rebuild strength.
Interventions may include:
-
Surgical or post-op protocols
-
Scar tissue management
-
Progressive loading
-
Return-to-performance planning
Why Rest Alone Isn’t the Answer
Short rest (24–72 hours) can help with swelling and pain—but prolonged rest delays healing and leads to:
-
Muscle atrophy
-
Joint stiffness
-
Compensatory movement patterns
-
Slower return to performance
👉 Active recovery beats passive rest. Research shows that guided movement and progressive loading improve outcomes far more than just “waiting it out.”
"The traditional RICE method has evolved; active recovery is now considered more effective in managing soft tissue injuries."
— Bleakley et al., British Journal of Sports Medicine, 2012
When to See a Physical Therapist
You should seek care if you’re experiencing:
-
Pain lasting more than a few days
-
Bruising or swelling after activity
-
Noticeable weakness or limited ROM
-
Recurring pain during specific movements
Move Better. Heal Stronger.
Muscle strains don’t have to sideline you. At OMNI Sport Performance & Physical Therapy, we help athletes and active adults recover faster—not just by treating pain, but by rebuilding strength and resilience so you can perform at your best.
