After that is muscular endurance. So this is how many repetitions you can typically do of a movement. So think of how many push ups in a row you can do, how many sit ups in a minute you can do, things that are typically in five to 50 repetition sort of range. And it is often or it is almost always local muscle. So what I mean by that is a push-up test is really how many reps that your triceps and pecs and deltoids can do. It is not a cardiovascular endurance. It is not a global physiological endurance. It's specific to, typically, one or a few muscle groups at a time. And this is why you have to do multiple tests for every group there. After that, now we've moved into number seven, which is what I call anaerobic capacity. This is more synonymous with maximum heart rate. And now we're actually looking at, rather than a single movement or muscle group, it is a total physiological limitation. So it is the maximum amount of work you can do in, say, 30 to 45 seconds, maybe even up to 120 seconds, of all-out work.
