How to Do the Side Plank
- Stand on your side, leaning against one elbow.
- Place the foot of the top leg in front of the other foot.
- Brace your core, and try to form and hold a straight line from your head to your feet.
The side plank is a bodyweight exercise to strengthen your obliques. The exercise can be made more challenging by placing your elbow or feet on an unstable surface (such as a Bosu ball, balance board, or suspended rings).
