30 Days of Daily Cardio Bring Mind and Body Changes
Women’s Health tracks one woman’s exercise habit through reported results and statistics.

Makari Espe, a Canadian YouTuber and former athlete, spent 30 days doing some type of cardio each day after deciding to change her routine. Her activities included running, hiking, water aerobics, spin, dance, and tennis, alongside weights and mobility work. The experiment was intended to explore changes in mood, stamina, and VO2 max, a measure of how much oxygen the body can use during exercise.
The effects appeared quickly. Espe felt more energetic and positive, enjoyed experimenting with unfamiliar activities, and noticed less fatigue during exercise. Running became a favorite, while her VO2 max increased from 33.76 at the beginning to 37.37 at the end, moving from “good” to “excellent” for her age. She also reported feeling stronger in the gym and more interested in activities she once found difficult.
The month brought harder moments, including tired legs, dehydration, and days when she did not want to continue. Those experiences showed her that recovery, stretching, strength work, and mobility belonged alongside cardio. Shorter 20-minute workouts helped her maintain the routine, and by the end she viewed daily movement as something she could keep doing. For adults trying to stay active and feel good, her experience highlights how enjoyment, variety, and a manageable routine can shape a lasting habit.
