Your body is incredibly smart. Whether you’re lifting weights or running a marathon, your body has to figure out a way to keep itself fueled and moving in the most effective way. The key to this fueling process is the use of different energy systems. As you train, try your best to work on all three systems discussed below for maximal results.
1. Creatine Phosphate System
The first one is the creatine phosphate system, which is used during short bursts of energy where movements only last 10 seconds or less. This system doesn’t use oxygen to replenish your energy stores in order to produce more energy at a faster rate. A great example is a deadlift—it requires a huge amount of energy, but it only lasts a few seconds.
2. Anaerobic Lactic System
The anaerobic lactic system takes a little more time than the creatine phosphate system, with movements lasting anywhere from 30 seconds to 2 minutes. This system also produces lactic acid. A perfect example is HIIT, or High Intensity Interval Training. It’s short and sweet, but you definitely feel the burn. If you’re new to HIIT, try this workout: do jumping lunges for a minute, rest for 30 seconds, then do burpees for a minute. Repeat the cycle for 15 minutes. It’ll get your muscles working and your heart rate up to improve your cardiovascular health—a win-win situation!
3. Aerobic System
The third system, known as your aerobic system, is most commonly referred to as cardio. While the term “aerobic” definitely takes me back to the ‘80s, there’s a lot more to it than just leg warmers and oversized bangs—it includes the most common form of cardio: running. Aerobic cardio lasts longer than 3 minutes and uses oxygen. It can be anything from hiking to running a marathon.
The great thing is, your health will improve, regardless of what energy system your body is using. You’ll reduce the risk of heart disease, improve your blood cholesterol, increase your heart function, and help your muscle mass grow. So whether you’re a gym junkie or you just want to be healthy, exercise should become a vital part of your daily routine.
