For many people in the gym, cardio is either seen as punishment or avoided completely. <\/span>Some believe it will harm their gains or burn muscle, while others use it excessively, hoping it will magically accelerate fat loss. <\/span>The truth sits somewhere in the middle: cardio is a very powerful tool when used correctly. It improves health, supports training performance, and can even help with body composition \u2014 but like anything in training, it has to be applied correctly and consistently.<\/span><\/p>\n

Let\u2019s take a look at what cardio actually does and how to use it depending on your goals.<\/span><\/p>\n

What Cardio Actually Improves<\/b><\/h3>\n

Cardiovascular training does a lot more than just burn calories. It helps creating a wide range of physiological adaptations that can benefit both <\/span>health <\/b>and <\/span>performance<\/b>.<\/span><\/p>\n

    \n
  1. \n

    Cardiovascular Health<\/span><\/h4>\n<\/li>\n<\/ol>\n

    Cardio strengthens the heart and improves circulation. Over time, this leads to better blood flow, lower resting heart rate, and improved oxygen delivery throughout the body. <\/span>These adaptations are one of the main reasons regular cardiovascular exercise is strongly associated with a lower risk of heart disease and improved long-term health and well-being.<\/span><\/p>\n

      \n
    1. \n

      VO\u2082 Max and Aerobic Capacity<\/span><\/h4>\n<\/li>\n<\/ol>\n

      Cardio improves your VO\u2082 max, which is basically your body\u2019s ability to utilize oxygen as you exercise. <\/span>A higher VO\u2082 max means your body can produce energy more efficiently, especially during prolonged or repeated efforts. <\/span>At the end of the day, this means better work capacity and improved endurance.<\/span><\/p>\n

        \n
      1. \n

        Reduced Fatigue During Workouts<\/span><\/h4>\n<\/li>\n<\/ol>\n

        Better aerobic conditioning can make resistance training feel less exhausting. <\/span>When your cardiovascular system is more efficient, you recover faster between sets and accumulate less fatigue during training sessions. <\/span>That leads to more productive workouts and better long-term progression.<\/span><\/p>\n

          \n
        1. \n

          Improved Metabolic Health\u00a0<\/span><\/h4>\n<\/li>\n<\/ol>\n

          Cardio improves insulin sensitivity and overall metabolic function. This can help your body regulate blood sugar more effectively and make it easier to improve body composition over time. <\/span>It also contributes to better nutrient partitioning \u2014 your body uses whatever you eat way more efficiently.<\/span><\/p>\n

            \n
          1. \n

            Increased Recovery and Blood Flow<\/span><\/h4>\n<\/li>\n<\/ol>\n

            Low to moderate intensity cardio can improve recovery by increasing circulation and promoting nutrient delivery to tissues. <\/span>This is why light cardio is a great pick on rest days to support active recovery.<\/span><\/p>\n

            Choosing the Right Type of Cardio<\/b><\/h3>\n

            Not all cardio serves the same purpose. <\/span>The type, intensity, and duration should always support your primary goal. <\/span>A simple way to gauge intensity is by using the percentage of your maximum heart rate (HRmax).<\/span><\/p>\n

            A rough estimate of HRmax is: <\/span>220 \u2013 age <\/b>(This is not 100% perfect, but good enough for practical use.)<\/span><\/p>\n

            Low-Intensity Cardio (LISS) ~50\u201365% of max heart rate<\/span><\/h4>\n

            Examples: walking, cycling, and incline treadmill, light rowing.<\/span><\/p>\n

            Primary fuel: mostly fat oxidation, with some carbohydrate use.<\/span><\/p>\n

            Benefits:<\/span><\/p>\n

              \n
            • Supports recovery<\/span><\/li>\n
            • Low fatigue cost<\/span><\/li>\n
            • Easy to maintain consistently<\/span><\/li>\n<\/ul>\n

              This type is ideal for general health, recovery days, and maintaining energy expenditure.<\/span><\/p>\n

              Moderate Intensity Cardio\u00a0<\/span>~65\u201380% of max heart rate<\/span><\/h4>\n

              Examples: steady-state running, rowing (more intense), longer bike sessions.<\/span><\/p>\n

              Fuel mix: both carbohydrates and fats contribute significantly.<\/span><\/p>\n

              Benefits:<\/span><\/p>\n

                \n
              • Improves aerobic capacity<\/span><\/li>\n
              • Builds endurance<\/span><\/li>\n
              • Moderately increases cardiovascular fitness<\/span><\/li>\n<\/ul>\n

                High-Intensity Cardio (HIT) ~80\u201395% of max heart rate<\/span><\/h4>\n

                Examples: sprints, intervals, circuits.<\/span><\/p>\n

                Primary fuel: carbohydrates (muscle glycogen).<\/span><\/p>\n

                Benefits:<\/span><\/p>\n

                  \n
                • Strong stimulus for VO\u2082 max<\/span><\/li>\n
                • Time efficient<\/span><\/li>\n<\/ul>\n

                  However, it also creates much more fatigue and should be used strategically, especially if muscle growth is the main goal.<\/span><\/p>\n

                  Timing Cardio Around Resistance Training<\/b><\/h3>\n

                  When combining cardio and strength training, timing is key! <\/span>If your main goal is muscle growth or strength, it\u2019s generally best to:<\/span><\/p>\n

                    \n
                  • Perform cardio after lifting, or<\/span><\/li>\n
                  • Separate cardio and lifting sessions by several hours.<\/span><\/li>\n<\/ul>\n

                    High-intensity cardio before strength training will reduce performance and take away from your ability to produce force during your workout. <\/span>Low-intensity cardio, such as walking, usually doesn\u2019t create this issue. <\/span><\/p>\n

                    Something to keep in mind: Just because low-intensity cardio uses a higher percentage of fat as fuel doesn\u2019t automatically mean it leads to greater fat loss.<\/span><\/p>\n

                    Fat loss ultimately depends on total energy balance over time, not which fuel source is used during a single workout.<\/span><\/p>\n

                    How Much Cardio Do You Actually Need?<\/b><\/h3>\n

                    For most people, a moderate amount of cardio provides significant benefits without interfering with strength training.<\/span><\/p>\n

                    A good starting point for many individuals is:<\/span><\/p>\n

                      \n
                    • 2\u20134 cardio sessions per week<\/span><\/li>\n
                    • Mostly low to moderate intensity<\/span><\/li>\n
                    • 20\u201340 minutes per session<\/span><\/li>\n<\/ul>\n

                      From there, volume can be adjusted to support individual goals. <\/span>Fat loss phases may require more cardio, while muscle-building phases often benefit from a smaller amount used mostly for health and recovery.<\/span><\/p>\n

                      The Takeaway<\/b><\/h3>\n

                      Cardio isn\u2019t the enemy of muscle growth. <\/span>When used intelligently, it can improve health, support recovery, and even make your strength training more productive. <\/span>Just like anything else, the key here is balance. <\/span>Use cardio as a tool \u2014 not as punishment and not as something to avoid completely. <\/span>Because the goal isn\u2019t just to build muscle. <\/span>It\u2019s to build a body that performs well and stays healthy in the long run.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
