How can one combine fasting on alternate days with fasting on Mondays and Thursdays?

Islam is a complete religion characterized by a diversity of acts of worship, some of which can be combined and some cannot. Fasting one day and breaking the fast the next is the best voluntary fast, and fasting on Mondays and Thursdays is another independent type, and they cannot be continuously combined. Therefore, the best is offered, and a Muslim must consider their energy and ability to continue voluntary work, because the most beloved deeds to Allah are those that are most consistent, even if they are few.
