Not only does ‘Core strength’ refer to sit-ups, but it also refers to the strengthening of the muscles in the glutes, the back and the abdomen. These three types of muscles are responsible for supporting the spine and maintaining the balance of the body. If you lead a sedentary life, strengthening these muscles is essential for maintaining your overall health.

Sitting at a desk for a long period of time can lead to lower back pain and a poor posture. However, strengthening the core muscles will relieve back pain and support your spine.

Why are planks so beneficial?

Planks are essential for strengthening your core muscles. Dr. Jinger Gottschall thinks that planks enhance the stability of the muscles, which promotes proper body posture and adequate alignment of the spine and supports a three-dimensional activation of the body, from the hips to the shoulders.

In addition, plunks offer countless health benefits, including:

• Toning up abs
• Reducing lower back pain
• Enhancing mood
• Increasing flexibility

As planks include several groups of muscles at the same time, it can be a bit challenging at the beginning. However, you should be able to hold planks for 4 minutes by the end of the plank challenge.
