I asked the question "Define fitness", and then went on to agree that middle distance running is a fair measure.
Once a man has speared an antelope, he has to run after it and retreive it before the cats can get it. - hence "evolved to do".
The dictionary definition is "
ability to transport oxygen and fuel to the muscles for a sustained period".
Running after an antelope for an hour until it dies, IMHO, is what humans should be best at. Not riding a wheeled machine or even smimming across a river. Not even kicking a pig's bladder round a field

Fitness may be defined as being the extent to which an individual can
repeat or
continue a given aerobic exercise within a certain timescale.
Within a regular training regime,
Intensity is the best PRODUCER of fitness. If you want to become fitter, it's always - within reason - better to upgrade the intensity of your workouts, instead of their volume or frequency. Be careful not to increase training volume & intensity at the same time - you will either feel 'rundown' or get injured (or both).
Carrying out some
intense training sessions is the optimal way both to
produce and
preserve fitness.
Running sessions (
once a week) along the following lines are good :
5-8 minute gentle warmup, then do . . .
40 seconds '*effort' and then just 20 seconds
jogged recovery; repeat this about 6 - 8 times. (40 seconds effort then 20 seconds recovery X 6-8 times). Over time, you should be able to do 12-15 (or more) of the efforts.
Finish with a 5-8 min warm-down.
* effort should be no slower than 800 metres pace. In 40 seconds, you should be covering between 150-200 metres.
Or
5-8 minute gentle warm-up, then do . . .
4 mins *effort (slightly over 10K race pace) followed by 1 minute jogged recovery. Repeat efforts 3 or 4 times. (4 minutes effort then 1 minute recovery X 3-4 times).
Finish with a 5-8 min warm-down.
* effort should be faster than you'd race 10K
When doing effort sessions, try to keep the level of effort consistent; eg you should not be doing 200 metres in the first 40 seconds effort and then 150 metres in the next.
During these sessions, the jogged recovery time does seem very short; but if you stick with them, within 10-14 days, you
will notice an improvement in your ability to recover after each effort.
