There were many ways for women to show their religiosity in the Middle Ages. The most obvious of course was by becoming a nun, entering a monastery for women. Although such nunneries became common in the late Middle Ages, when a large proportion of the nuns had entered the cloister as girls, for much of the Middle Ages such houses were far outnumbered by male monasteries.
In the early and high Middle Ages, most of the nuns did not enter as girls but rather as mature women. Men too did not always enter as boys; the Cistercian order, for example, was made up primarily of monks who had converted as young men, and many an elderly man decided to improve his chances at heaven by spending his final year or two as a monk. But there were a whole lot of nuns who had entered the house in middle age, not old age, usually because they were widowed--a common event when women tended to marry much older men.It was these experienced middle-aged women who tended to become abbess. At the double-monasteries of the early Middle Ages and of twelfth-century houses like Fontevraud, where a male house and a female house had a single head, the head was always a middle-aged woman.
But how else could a woman be religious? Nunneries usually followed the same Benedictine Rule as male monasteries, but just as there were houses of male canons, who lived more or less like monks but who also served as priests for their community, there were some houses for canonesses. Although of course they did not serve as priests, they might take care of people at a hospital. (Even today, nurses in Britain are called Sister, a reminder of this old function.)
Canonesses lived in a cloistered setting, like nuns, but one could still be a religious woman outside the cloister. In medieval cities, from the thirteenth century onward, there grew up forms of the religious life for women where the women continued to live in their own houses and do their normal activities but still practice a more contemplative life. They might have a rule formally endorsed by a bishop and practice chastity as well as meeting regularly for prayer.
But some of these lay sisterhoods did not bother with a formal rule. They followed a life that combined religiosity in both a public and private setting but took no vows. From their point of view, they were living like the original apostles as described in the Book of Acts in the Bible. The Beguines, found primarily in cities of Flanders, sought to help their fellow citizens through good works as well as trying to be fair and honest in their own commercial dealings. They met regularly to encourage each other and to pray together.
The danger was that, without vows or formal oversight from the church hierarchy, they were considered (at least by the church hierarchy) to be in danger of slipping into heresy. Some of them did, making up their own versions of religious doctrine--which of course they believed was true Christianity (the bishops disagreed). Some got into serious trouble and ended up shipped off to real nunneries. Some were allowed to continue as long as they kept quiet about it.
And then there were the recluses, women who set themselves up in a tiny house build on the outside of a church. They would of course need the approval of the priest or bishop. This practice was more frequent before nunneries became common. The woman in essence was a hermit in her cell, except that she was usually in the middle of town or village, not out in the woods, where everyone agreed (even including the women) females ought not to be by themselves. Most of these recluses had enough food to live on donated by the pious and regularly attended Mass in the adjoining church. But in an extreme version the recluse might be walled up in her cell and not leave at all.
These recluses are often referred to as "anchorites" by British historians, although no anchor was involved, and there is no medieval cognate for the term.
Some of ways medieval women showed their religiosity must have been very hard on their bodies. But as Peter Abelard pointed out in the early twelfth century, because women's bodies were weaker than men's, their virtue was so much greater in enduring physical privation.
