One of the things that bothers people about many forms of muscle exercise is “how many reps?”.

Well, I remember a few (quite a few!) years ago, reading a book by a (Dr.) Someone who had worked on systems for keeping astronauts as fit as possible in space.

He stated that it was the first repetition of any form of exercise that gave the most physiological benefit, after that the effect lessened rapidly.

The message being that often 2 reps would be sufficient to maintain muscle fitness and after about 4 or 5 the gains were so small that it was not worth the time and effort – you would be better off doing something else.

I go along with this! – few reps but done with real concentration are much better than dozens without concentration and “good form”.

How about that for easy fitness!

Can’t see a runner getting much out of just doing 2 paces in training though.
