Frequently Asked Questions
What is a good resting heart rate?
60-100 bpm is normal; well-trained athletes often sit at 40-60. A lower resting rate usually means better cardiovascular fitness.
What zone should I train in?
Moderate (50-70%) for fat-burning and base fitness; vigorous (70-85%) for cardio improvement. Mix both across the week.
