New pictures (photos) for fitness exercises

More than 50 pictures (photos) have been added in the Exercises articles so as to illustrate them.
These images mostly represent Arnold Schwarzenegger, one of the greatest bodybuilder of all times (7 times M. Olympia), who tried an huge number of workouts during his career !
To diversify exercises does not allow only to fight boring period, but also to work the musclesstimulation can allow to pass one “stage” and to start a new phase of progress.

Even if photographies are not in color (except a few ones), I feel them quite instructive and interesting.
