Personal Training for Aerobic Fitness: The Science Behind VO₂ Max and Cardio Gains

What does aerobic fitness really mean — and how can personal training help you improve it?? Amy Hudson and Dr. James Fisher break down VO₂ max, heart rate, and the science behind combining strength training with interval workouts.

From boosting cardiovascular health to reducing fatigue and disease risk, they explain how targeted personal training can transform your conditioning and overall well-being.

• Amy Hudson and Dr. James Fisher look at the benefits of having increased aerobic capacity, how to increase it and the role of both strength training and brief interval training in aerobic capacity.
• One of the most common terms used in scientific literature is VO₂ max which represents the maximum volume of oxygen our body can take up and use.
• Dr. Fisher explains that whenever we talk about cardiovascular fitness or cardiorespiratory fitness, it’s about how well oxygen can move around our body.
• Dr. Fisher and Amy talk about why VO₂ max and CO2 (carbon dioxide) are important in terms of their fitness.
• Did you know that your conditioning level, to some extent, can determine what exercise level or exercise intensity you can work at to maintain working aerobically?
• Not only daily fatigue but also your sleep, risk of depression and anxiety, risk of coronary artery disease and hypertension, and the risk of diabetes are all positively impacted by an improved aerobic conditioning.
• Dr. Fisher approaches the audience question: Does knowing one’s resting heart rate indicate anything to that person about their current state of cardiovascular health or aerobic capacity?
• As you improve your fitness, you improve what’s called cardiac output and stroke volume.
• If you’re curious about your maximum heart rate, you can calculate it by taking the number 220 and deducting your age from it…
• Amy brings interval training and glycogen into the conversation.
• Dr. Fisher explains that the importance of having a strength training workout and then doing concentrated cardio at the end is actually great because it serves as this glycogen dump.
• Dr. Fisher goes into EPOC – Excess-Post Exercise Oxygen Consumption – and the specificity of an action and, specifically, a sport itself.
