Quick Win
Aerobic exercise is important for overall health, including brain health. Spend 20–30 minutes today doing a moderate-intensity workout.
Try This Today
- Choose your moves. What’s manageable today? A brisk walk outdoors or a hike on a nearby trail? A bike ride? Good indoor options include treadmill walking, aerobic dance classes such as Zumba and online exercise videos. (Check with your doctor before starting a new exercise program.)

Why
Large-scale population studies have linked getting regular exercise with better brain function later in life. Clinical research has shown benefits, too. After six months of supervised aerobic exercise, 206 middle-aged and older adults showed improvements in several aspects of cognition, including executive function (the ability to do things such as managing time and planning), according to a 2020 report in Neurology. In a study of 30 adults with mild memory problems, half did a year of aerobic exercise training, and half did a year of stretching. The aerobic exercisers experienced improved memory performance. Those results were published in 2020 in the Journal of Alzheimer’s Disease. Today’s a good day to start building the hab
