Again, I don't understand the question. All the monks & nuns I know, from Theravada/ Zen/ Vajrayana traditions, get more daily rigorous exercise than most lay people I know. The exercise looks different because the motivation is from a practical necessity (walking, daily prostrations, etc.) instead of vanity (pumping iron at a gym to build the perfect beach body.)
The Theravada monks I visit walk almost 8 miles a day, including some steep inclines. They also engage in some physically rigorous labor in a days work: chopping and hauling wood, building construction, raking and bagging leaves, etc. During the winter they do a lot of cross country skiing, and hiking in the summer. The Zen nun I visit is going to the gym for physical therapy following an injury, but also rides bikes and has physically demanding chores. Vajrayana monastics do all the above, plus an amazingly rigorous schedule of prostrations. Try 10 full-floor prostrations, my heart is pounding like crazy. Imagine doing 108 in a day, and that is on the low end of what is typical.
