Fast during Shaban & join it with Ramadan .

The Prophet Muhammad (PBUH) was known for his devotion to Allah and his practice of fasting. He would fast every day, but he would also fast an entire month out of the year, which was the month of Shaban. This is a special month in Islam because it is a time for Muslims to reflect on their lives and prepare themselves spiritually for the upcoming holy month of Ramadan. During this time, Muslims should focus on prayer, charity, and other acts that will bring them closer to Allah. By fasting during this time, they are able to show their dedication and commitment to Allah's teachings. Additionally, by joining Shaban with Ramadan they are able to make up any missed days from previous months or years when they were unable to fast due to illness or other reasons.
