What the research actually says
Most writing about cycles and training repeats the same four-phase template. These pieces start from the studies instead — including the ones whose findings are inconvenient.
Can you cycle sync on birth control? Yes. Here's how

Does cycle syncing work? Most women feel their cycle, and symptoms like fatigue and cramps are well documented. Phase-based plans don't build extra muscle. What the studies say and what to do.
