Wide-grip latissimus dorsi pull-down

Researchers at the University of Miami had 10 experienced bodybuilders complete a wide-grip anterior neck pull-down with a forward and reverse grip, followed by a wide-grip posterior neck pull-down while using electromyography to record muscle activity. A slight backward lean mimicked the pull-up movement. After a long-term follow-up, the 10 gym participants had a very visual increase in latissimus dorsi width.

There can be many dimensions of exercise classification, the reason why the dimension of aerobic and anaerobic is chosen for classification is because the classification of this dimension is closely related to your fitness purpose. You need to rationalize the ratio of aerobic to anaerobic exercise time, etc. to achieve your fitness goals. The following is a brief introduction to aerobic, anaerobic exercise, and the combination of the two.

Aerobic exercise, as the name suggests, is a sport performed in a state of sufficient oxygen, any longer duration, rhythmic, heart rate maintained at 60% to 80% of the maximum heart rate can be called aerobic exercise.

Anaerobic exercise, anaerobic exercise, as the name suggests, is intense exercise in a state of "oxygen deprivation", most anaerobic exercise is a high intensity, instantaneous exercise, so it is difficult to last a long time, and the fatigue elimination time is also slower (the process of glycolytic metabolism is more troublesome.) Anaerobic exercise is only a relative definition, at this time there must be aerobic exercise part of the existence, just oxygen can not fully meet, anaerobic part more than the aerobic part. Like weightlifting, sprinting, fighting, such as short bursts of exercise almost all belong to anaerobic exercise, and slow, sustained muscle power movement also belongs to anaerobic, such as the most typical bodybuilding training. Anaerobic training can be loosely referred to as strength training. You can simply understand that any exercise that involves lifting weights to move heavy objects is anaerobic. Strength training can be a good way to deplete your sugar reserves.

But to be clear, there is no clear line between anaerobic and aerobic. For example, running, if it's a sprint, it's basically anaerobic. Because it is short, explosive, in such a short period of time oxygen is almost too late to participate in energy supply. The real development of muscle movement is anaerobic exercise, this you compare the body type of long-distance runners and sprinters will know, sprinting to be much stronger, long-distance runners are leaner body type.

The combination of aerobic and anaerobic exercise, why say so, is that this type of exercise inside the aerobic and anaerobic part may be more balanced, not very good to define the aerobic or anaerobic, so I put it into the combination of aerobic and anaerobic exercise. For example, HIIT, when high-intensity exercise, there must be a lot of part of anaerobic, than the frequency of relatively stable exercise, anaerobic part of the proportion of more, but less than the proportion of strength training anaerobic. And like crossfit, itself is the type of exercise that emphasizes the combination of aerobic and anaerobic, so it can also be considered a combination of aerobic and anaerobic exercise
