When it comes to training, most people are unaware of the body’s three primary energy systems and which one is dominant during their workouts. Understanding these systems can be the key to maximizing fat loss and improving overall fitness.
The 3 Primary Energy Systems
ATP-PC System
This system provides immediate energy for short bursts of high-intensity activity, lasting about 10 seconds. Think of a sprint or a heavy lift.
Aerobic System
The aerobic system uses oxygen to fuel low to moderate-intensity activities over an extended period, such as jogging or cycling.
Lactic Acid (Glycolytic) System
This system kicks in during moderate to high-intensity efforts that last up to two minutes. It produces lactic acid, which you feel as the familiar “burn” during intense exercise.
Which Energy System Should You Focus On?
While all three systems are essential, tapping into the Lactic Acid Energy System is especially effective for burning excess body fat. This system can be activated through Time Under Tension (TUT) training, a technique I’ve been using since the 1990s.
What Is Time Under Tension (TUT)?
TUT involves keeping muscles under consistent tension for a prolonged period during each set of an exercise. This technique generates lactic acid, leading to the “burning” sensation during intense training.
Why Is TUT Crucial for Fat Loss?
Build Strength and Endurance
Training muscles under tension enhances their capacity to work harder and longer.
Burn More Calories
Engaging the Lactic Acid Energy System boosts calorie burn, helping you shed unwanted fat more effectively.
Improve Fitness and Resilience
Regular TUT training makes you stronger, more resilient, and better conditioned overall.
How to Incorporate TUT Into Your Training
Perform exercises with slow, controlled movements to extend the time your muscles stay under tension.
Focus on maintaining proper form and breathing as you work through each rep.
Gradually increase the duration of tension as you build strength and endurance.
By activating the Lactic Acid Energy System, you’ll not only burn more fat but also improve your overall fitness.
