Speed Up Your Cardio To Tone Up Your Body

Remember this: cardio exercise doesn’t have to be aerobic! Aerobic exercise is an activity that is done continuously for more than 2 straight minutes (like treadmill and biking). If you want to tone up your body and look more athletic (but not too bulky), you should perform the majority of your cardio exercise using sprint intervals. Doing sprint intervals will activate your bulky fast-twitch muscle fibers to give you a more lean and toned body. Just take a look at an athlete who competes in a speed sport. Their bodies are “ripped” for a reason (most of their training is fast and explosive). Research has proven that the heart-health benefits of anaerobic exercise is superior to aerobic exercise.
