What additional accessory can be used to increase the challenge of a plank?

Using a weighted vest to increase the challenge of a plank is an effective strategy because it adds extra resistance that the body must stabilize against. When performing a plank, the core muscles—including the abdominals, obliques, and lower back—must engage to maintain the position. Adding weight increases the demand on these muscles, enhancing strength and endurance.

The additional weight from the vest compels the body to recruit more muscle fibers and can lead to greater improvements in core stability and overall strength. Furthermore, as the body works harder to maintain the plank position, it promotes better muscular adaptation and growth, making your workout more effective.

In contrast, while resistance bands and balance boards can also provide challenges to a plank, they do so through different mechanisms. Resistance bands introduce an element of tension, changing the dynamics of the exercise, while balance boards require stabilization and balance, which may distract from the primary focus of core strengthening. Lastly, a yoga mat primarily serves a comfort purpose during exercises and does not inherently increase the challenge of the plank itself.
