A few years ago, planking was everywhere. While the craze has subsided, the plank is no fad exercise. In fact, planking has many benefits.
It's great for your abs and helps develop deep inner core muscles.
Planks reduce back pain. It requires minimal movement while contracting all layers of the abdominal fascia. Strengthening your core helps reduce lower back pain.
Planks also increase flexibility, improves posture and boosts your metabolism. Planking daily will burn more calories than other ab exercises. The muscles you're strengthening by doing this exercise daily will ensure that your metabolic rate remains high even when sedentary.
