Tight hips can cause various issues, including:
Poor Balance and Posture – The front of the hips, the hip flexor, is a major stabilizer of the pelvis. Therefore, if the hip flexors are weakened, it can lead to imbalance and poor body posture.
Muscle Imbalances – The extended periods of sitting shorten and tighten the hip flexors. In a sitting position, the glutes and the hip extensors are being overstretched, but they are also weakened as not all muscle groups are used.
Back Pain – The tight hip flexors and the overstretched muscles will force the pelvis to be pushed forward, unnaturally tilted, and thus pull the muscles of the lower back.
If you are spending most of your time sitting, you could benefit a lot from doing these stretching exercises. They will improve the hip mobility and increase your power. Moreover, you will boost the flexibility of your hips.
