Plastic surgeon sparks controversy by warning against running as exercise

A New York plastic surgeon sparked controversy on social media by warning against running as a form of exercise. Dr. Gerald Imber, known for blunt health commentary, posted a message that he is tired of saying running destroys the body, arguing that while it delivers a rush, it can damage the knees, ankles and hips, accelerate facial aging, and even contribute to a gradual loss of height from constant pounding. He urged people to consider cycling as a safer alternative for joint and long-term health.

The video quickly went viral and stirred a backlash. Some runners defended the activity, citing decades of participation without major injuries or noting personal longevity. Others said they have experienced joint pain after years of running and found walking or cycling easier on their bodies. The online clash reflected a broader fracture within fitness circles over whether running is a fountain of youth or a high-impact habit that wears people down over time.

Sports Medicine Australia, a leading body on athletic health, says both running and cycling are effective cardiovascular workouts, but they differ in impact. Running places more stress on knees, hips and ankles and can strengthen bones while raising risks of stress fractures, shin splints and joint wear. Cycling, by contrast, is low-impact on joints and generally seen as more sustainable for older adults, though it may not boost bone density as effectively. Many experts advocate a mixed approach: include lower-impact activities like cycling, swimming and walking, supplement with strength training, and include occasional running to optimize bone health, cardiovascular fitness and joint protection.

Even as the debate continues, health professionals emphasize balance and individual differences. The exchange mirrors a broader conversation about how people should structure long-term exercise plans, particularly as age and wear influence joints and mobility. In the meantime, athletes and casual exercisers are encouraged to tailor routines to their bodies, varying intensity and impact while prioritizing overall fitness and injury prevention.
