And I LOVE teaching planks for one simple reason. Sure, they are among the best exercises to train strong cores and healthy backs. And yes, they're a safe way for nearly anyone of any height, weight, or ability to develop spine stability and core awareness. Planks are also popular because they help athletes like golfers to hit farther, martial artists to strike harder, and tennis players to react faster. And planks can also be the ultimate fitness tool for full-body strength, endurance, and functionality in sports and life with the added BONUS of a six-pack, chiseled obliques and sculpted glute, chest, back and shoulder muscles.
