The Norwegian four-by-four protocol consists of alternating four minutes of high-intensity work with four minutes of recovery. Doing this protocol just once a week is highly effective.
A woman's body has a highly sensitive hypothalamus that stops reproduction and retains body fat during energy deficits to ensure evolutionary survival during scarce periods.
Reframing physical stress around recovery rather than 'overtraining' makes it mentally easier for women to feed themselves adequately and schedule rest days.
Since perimenopausal women already have high baseline cortisol, exercising in the middle intensity ranges keeps cortisol elevated and prevents the body from recovering.
Because women lose lactate-producing muscle fibers as they age, performing high-intensity exercise is critical to feed the brain lactate and prevent metabolic issues tied to Alzheimer's.
