Walking is good for you, but here’s why walking backward might be even better.

Not only does walking backward challenge your muscles in new ways, but it also improves balance, coordination, and cognitive function. It can help strengthen different muscle groups and enhance your overall fitness.

Just try not to fall. Or laugh. Walking backward can feel a bit awkward at first, but with practice, it becomes an enjoyable and beneficial addition to your exercise routine.
