What is zone 2 exercise?
Sources:
Zone 2 exercise is a type of cardiovascular workout that focuses on maintaining a moderate level of exertion, allowing you to sustain the activity for an extended period. This form of exercise targets improving aerobic capacity and efficiency by using fat and glucose as energy sources without pushing into an anaerobic state, which relies more on glycogen stores for energy. Here are some key insights about Zone 2 exercise from various experts:
-
Purpose and Intensity: Zone 2 exercise is performed at a moderate intensity where you can still hold a conversation. It is typically at 50% to 60% of your maximum heart rate, acting as a bridge between very light activity and more intense cardio sessions. This exercise zone enhances your aerobic efficiency, essential for endurance and overall cardiovascular health 1 2 3 4.
-
Activities: Examples of Zone 2 activities include brisk walking, light jogging, moderate cycling, swimming, rowing, or hiking. The goal is to maintain a steady pace that raises your heart rate without overexerting yourself. Each person's Zone 2 can look different based on their fitness level. The idea is that you should be able to talk but not necessarily want to carry on a lengthy conversation comfortably 1 2 5.
-
Health Benefits: Regularly engaging in Zone 2 workouts can improve metabolic health, enhance mitochondrial health, and maximize fat oxidation. It helps build a strong aerobic base, which is foundational for endurance training and improving overall fitness 5 2.
-
Training Recommendations: Experts suggest incorporating Zone 2 exercise into your routine for at least 150 to 200 minutes per week to support health span and lifespan. This can be broken down into several sessions per week—from 30-minute activities to longer sessions such as hikes or jogging 2 4.
Zone 2 training offers a balanced approach to cardiovascular health, suitable for both fitness enthusiasts and those new to exercise.
