Backward walking vs running: Which is safer for the knees?

Running is usually introduced as the best exercise regimen for health, yet it is highly stressful on your knees. Every time your foot strikes the ground, your knee joints absorb a significant amount of impact. This over time can cause pain, swelling, or even eventual joint issues, particularly if your knees are weak to begin with.

Backward walking or what is known as "retro walking", by contrast, is easier on the knees. It rearranges how your muscles and joints work. As you walk backwards, you instinctively engage your calves, hamstrings, and glutes more, which help stabilize the knee and decrease pressure against the front of the joint. This can cushion the cartilage and lower the threat for injuries that running typically carries with it. Take a look




Another advantage is coordination and balance. Walking backward tests your body differently, using muscles that aren't as involved in normal forward walking or running. Not only does it make the muscles surrounding your knees stronger, but overall stability improves, which can avoid falls and other injuries.

How is backward walking beneficial for the kneesBackward walking can also be useful in rehabilitation. Physical therapists can suggest it to patients recovering from knee injuries or surgery since it is an excellent exercise without putting any additional stress on the joint. You may begin gradually on a flat surface and progress gradually towards increased distances as your muscles become stronger.

What research says

A study published in PubMed Central, under the title,The Immediate Effect of Backward Walking on External Knee Adduction Moment in Healthy Individuals, demonstrated that backward walking leads to meaningful reductions in medial knee joint loading when compared to forward walking. Backward walking significantly reduced key indicators of medial knee load, including both early and late peaks of the external knee adduction moment (EKAM), as well as the knee adduction angular impulse (KAAI). These reductions suggest a decreased risk of stress-related progression of knee conditions like osteoarthritis.

These findings support that backward walking as a promising low-impact exercise that may help reduce joint stress and benefit individuals recovering from injury or managing chronic knee conditions.

Precautions should be observed with safety. Make sure the room is empty and level, put on supportive shoes, and start gradually to avoid loss of balance. Others even lean against a railing or wall at first.

Other benefits of walking

Builds lower body strength

It reverses the normal heel-to-gait, activating different muscles. It activates the quadriceps, glutes and calves more intensely, as the motion requires greater effort to stabilize and propel the body. Over time, it improves strength, endurance and tone muscles in legs.

Improves balance and gait

It enhances walking speed, balance and coordination, especially after injuries or in rehabilitation. Research published in PubMed Central states that people who are recovering from stroke walked backward on the treadmill for 30 minutes, had better balance, walking speed, and cardiovascular health.

Burns more calories than forward walking

Walking backward requires more muscle effort than regular walking, causing one to burn more calories. Research published in PubMed central says that backward walking or retro walking uses more energy than forward walking and oxygen consumption and the heart rate increases in turn.

Adding the gait pattern of walking backwards into their routine workout, only a few times a week, can help the knees bypass the high impact of running without losing the heart rate. Practicing it long-term can create strength, balance, and joint integrity, all while providing the knees with a lower-impact workout. Over time, backward walking can also improve coordination, enhance proprioception (the body’s sense of position), and engage muscles that are often underused in forward motion, such as the calves, quadriceps, and shins. This simple addition can complement regular cardio and strength training, promoting overall lower-body resilience and reducing the risk of knee injuries.
