Planks are one of my go-to exercises for building deep core strength and stability. They’re easy to modify for beginners, can be done in different ways as you get stronger, and don’t require any equipment (aside from a yoga mat for cushioning).
Like any exercise though, proper plank form is crucial. While planks are relatively simple to do, I often see the same form errors that reduce their effectiveness, reinforce faulty movement patterns, and leave you more susceptible to injury.
