A study has compared the bones of Neolithic, Bronze Age, and Iron Age women to those of modern female athletes:
Grinding grain for hours a day gave prehistoric women stronger arms than today's elite female rowers, a study suggests. The discovery points to a "hidden history" of gruelling manual labour performed by women over millennia, say University of Cambridge researchers. The physical demands on prehistoric women may have been underestimated in the past, the study shows. In fact, women's work was a crucial driver of early farming economies.
"This is the first study to actually compare prehistoric female bones to those of living women," said lead researcher, Dr Alison Macintosh. "By interpreting women's bones in a female-specific context we can start to see how intensive, variable and laborious their behaviours were, hinting at a hidden history of women's work over thousands of years."

Sorry but your education on agriculture is off by a few centuries: https://en.wikipedia.org/wiki/Three-field_system [wikipedia.org]
Similar to your description, from early Mesopotamia until the dusk of Rome you had the Two-field system where you planted once a year. But from around 800ad Europeans were planting twice to three times a year.
