You can use the mindfulness of a yoga practice to help you find the proper body position in plank to help you build core strength.
Plank is a pinnacle posture for building strength. But it's really only effective if you do it correctly.
This is where the practice of yoga can be really powerful when doing a plank because doing it properly requires a lot of body awareness.
Try plank in its traditional form on the floor, hands under the shoulders and your feet back. Notice if you are in a nice straight line like a board. Bring body awareness to notice if your hips are falling towards the floor or if you're even just slightly piking up. You want to do your best to be in that place right in the center where your body is in a straight line.
If you become aware that you are sagging down or lifting up, try doing the plank posture from a chair. It's more important that your form is correct by being in a straight line then being on the floor.
If while using the chair, you become aware that you are still not in a straight line, do the plank from the wall. Place your hands on the wall with your feet back. Now once again check in to see if you can keep the body straight.
Once you are aware in which variation of plank you’re able to maintain a straight line, practice holding that posture to build the strength. Gradually progress to the other variations.
Combining the body awareness of yoga with the strength of the plank pose can really transform what you can do for your body and for your mind.
Try it today I think you'll find that body awareness really makes a difference.
