Prehab: How Exercise Before Surgery Improves Your Recovery

What Is Prehab?

Prehabilitation (prehab) is exercise and preparation before surgery. The concept is simple:

The stronger and fitter you are before surgery, the better you'll recover after.

Research supports this across many surgery types:

  • Joint replacements
  • Heart surgery
  • Abdominal surgery
  • Cancer surgery
  • Spinal surgery

    • Why Prehab Works

    Physical Benefits

  • **Stronger muscles** — Less weakness after surgery
  • **Better cardiovascular fitness** — Handle surgery stress better
  • **Improved range of motion** — Easier rehab after
  • **Better nutrition** — Improved healing capacity

    • Psychological Benefits

  • **Less anxiety** — Preparation reduces fear
  • **More control** — Active role in recovery
  • **Realistic expectations** — Know what's coming
  • **Better coping** — Skills for post-op challenges

    • Recovery Benefits

  • **Shorter hospital stays**
  • **Fewer complications**
  • **Faster return to function**
  • **Less pain medication needed**
  • **Better long-term outcomes**

    • General Prehab Principles

    1. Start Early

    Ideally 4-8 weeks before surgery. Even 2 weeks helps.

    2. Get Cleared

    Talk to your surgeon before starting. They'll advise on:

  • Activities to avoid
  • Any restrictions
  • Specific focus areas

    • 3. Focus on Relevant Areas

    Target muscles and functions affected by your surgery.

    4. Include Cardio

    Cardiovascular fitness helps you handle surgery and recover faster.

    5. Practice Post-Op Movements

    Learn exercises you'll do after surgery while you can do them pain-free.

    Prehab for Common Surgeries

    Knee Replacement

    Focus: Quad strength, range of motion, walking endurance

    Key exercises:

  • Quad sets (tighten thigh, hold 5 seconds)
  • Straight leg raises
  • Heel slides
  • Mini squats
  • Stationary cycling
  • Walking

    • Goal: Strong quads and full extension before surgery

    Hip Replacement

    Focus: Hip and core strength, walking endurance

    Key exercises:

  • Bridges
  • Clamshells
  • Hip abduction (leg lifts to side)
  • Mini squats
  • Core exercises (dead bugs, bird dogs)
  • Walking or cycling

    • Shoulder/Rotator Cuff Surgery

    Focus: Shoulder strength and mobility

    Key exercises:

  • Rotator cuff strengthening (external/internal rotation)
  • Scapular exercises
  • Range of motion (as tolerated)
  • Posture exercises

    • Note: If in pain, focus on what you can do without increasing symptoms.

    Spinal Surgery

    Focus: Core stability, leg strength

    Key exercises:

  • Dead bugs
  • Bird dogs
  • Bridges
  • Walking
  • Pelvic tilts
  • Leg strengthening

    • Avoid: Movements that increase your pain or are restricted by your surgeon.

    Abdominal/Cancer Surgery

    Focus: Overall fitness, breathing

    Key exercises:

  • Walking (as much as tolerable)
  • Breathing exercises
  • General strength training
  • Core activation (gentle)

    • Cardiac Surgery

    Focus: Cardiovascular fitness, upper body strength

    Key exercises:

  • Walking or supervised cardio
  • Light upper body exercises
  • Breathing exercises
  • May need supervised program

    • Sample Prehab Program

    4-6 Weeks Before Surgery

    Daily:

  • Walking 20-30 minutes
  • Gentle stretching

    • 3x/week:

  • Strength exercises targeting surgery area
  • Core exercises
  • 20-30 minutes

    • 2-4 Weeks Before Surgery

    Daily:

  • Walking 30+ minutes
  • Stretching
  • Practice post-op exercises (learn them now)

    • 3x/week:

  • Continue strength program
  • May increase intensity if tolerated

    • 1 Week Before Surgery

  • Maintain activity but don't overdo it
  • Focus on rest and nutrition
  • Practice deep breathing
  • Ensure home is ready for recovery

    • Nutrition in Prehab

    Good nutrition supports recovery:

  • **Protein** — For muscle and tissue repair
  • **Vitamins C and D** — Wound healing and immune function
  • **Zinc** — Healing
  • **Adequate calories** — Energy for recovery

    • If you smoke, quitting before surgery significantly improves outcomes.

    Psychological Preparation

  • Learn about your surgery and recovery
  • Practice relaxation techniques
  • Visualize successful recovery
  • Set up post-op support (help at home, etc.)
  • Ask questions—know what to expect

    • What If I'm Already in Pain?

    Pain can limit prehab, but:

  • Do what you can without increasing symptoms
  • Water exercise may be tolerated better
  • Focus on unaffected areas (cardiovascular, other limbs)
  • Isometric exercises may be tolerable
  • Something is better than nothing

    • When to Start

    Ideal: 6-8 weeks before surgery

    Good: 4 weeks before

    Helpful: Even 2 weeks before

    Don't skip prehab even if surgery is soon. Any preparation helps.

    The Bottom Line

    Prehab is one of the best things you can do for your surgical outcome:

    1. Start as early as possible

    2. Focus on surgery-specific exercises

    3. Include cardiovascular fitness

    4. Practice post-op exercises before surgery

    5. Address nutrition and mental preparation

    6. Clear your plan with your surgeon

    Going into surgery fit and prepared sets you up for the best possible recovery.
