Core: Abdominal and Lower Back Exercises
By Lottie Olson
How to Do a Straight Arm Plank
In a straight arm plank, the hands are positioned under the shoulders. This core exercise builds the abdominals and back muscles.
Get into plank position by supporting your body weight on your hands and toes.
Hands should be placed directly under your shoulders.
Keep your abdominals contracted and your back straight, eyes ahead of you.
Hold this position for as long as you can, building up to 1 minute.
