ABOUT THIS EPISODE
Nikki Fraser holds master's degrees in kinesiology and health psychology. She explains why high-intensity interval training targets visceral fat better than moderate cardio, how the 10x1 protocol works (one minute hard, one minute rest, 10 times), and why even 3-4 minutes of vigorous activity per day reduces mortality risk based on VILPA research.
Nikki covers how often to do HIIT without overtraining, why consistency matters more than perfection, how to track workouts for accountability, and why recovery capacity changes with age. This episode reveals practical ways to add intervals into busy schedules and how community-based training helps maintain long-term consistency.
