Levels of impact


“This study provides evidence suggesting that CEOs’ physical fitness has a positive impact on firm value, consistent with the beneficial effects of fitness on, e.g., cognitive functions, stress coping and job performance. CEO fitness is also associated with higher firm profitability and higher mergers & acquisitions announcement returns.”

- Limbach, Peter; Sonnenburg, Florian (2015): Does CEO FITNESS matter?

“Physical fitness is likely to benefit CEOs as it moderates stress and promotes cognitive functions and executive-control processes, self-esteem, work behavior, and performance. Accordingly, fit CEOs can be expected to better stand their high work stress, to be less exhausted, more efficient and better performing, and to ultimately be associated with a higher firm value.”

The effect of training

Training increases overall job performance and productivity. This beneficial effect is due to:

  • more quantity of work performed in the same time

  • a better quality of life and mood

  • less effort exerted to perform the work

  • a better relationship with the team

  • a better stressmanagement

  • better return to work after sickness absence

  • less sickness absence

The effect of nature

The nature aspect in which the GRAM goals are all taking place hold great influence on creativity and sleep quality.

Exercise in nature heightens the creative part of the brain and sleep quality showed to be enhanced. This latter is partially do to a reduced exposure to artificial light.
