What is the best way to avoid rug burn resulting in a friction sore from sit ups Is a yoga mat with a towel under it better than a regular exercise mat because it doesn't move around?

To avoid rug burn and friction sores during sit-ups, using a yoga mat can be effective as it provides cushioning and stability. Placing a towel underneath the yoga mat can add extra protection and help keep it in place. However, a quality exercise mat designed for movement may also offer sufficient grip and comfort. Ultimately, the best option is one that feels secure and comfortable for your specific workout environment.
