Plank Jack
The Plank Jack is a dynamic variation of the traditional plank that not only strengthens your core but also raises your heart rate. This exercise combines the stability of a plank with the cardio of jumping jacks, making it an excellent addition to any workout.

-
2
Make sure your abdominal muscles are engaged and your back is straight.
-
3
Jump your feet out to the sides, similar to the movement of a jumping jack, while keeping your upper body stable.

Common Mistakes
- ! Allowing the back to sag: Make sure to keep your abdominal muscles engaged to keep your back straight.
- ! Moving too quickly: Although speed can be a factor, it is more important to perform the movement in a controlled manner with proper form.
- ! Overloading the arms: Focus on using your core to maintain stability.
Targeted Muscles
The Plank Jack targets multiple muscle groups, including the rectus abdominis (abdominal muscles), the obliques, the shoulders, the chest, and the glutes. The leg muscles are also trained during the jumping movement.
Possible Alternatives
- Plank Jacks on your elbows: For those who want to reduce strain on the wrists.
- Step to the side instead of jumping: For a less intense variation.
- Add a push-up between the jacks: For an extra challenge.
