Abstract
New technologies are being invented and energy demand is increasing. Growth of population has always been and will remain one of the major causes of energy demand. Science is therefore looking for new major and minor energy resources to keep world in progress. The main focus of energy engineering and technology in the field of energy generation is to harvest energy by any mean from any source. A theoretical research is introduced in this paper which will contribute its reasonable share in the field of renewable and green energy sector. This energy generating system is named as energy generating gymnasium system (EGGS). The core idea behind this energy harvesting system is that, the human being is also a source of renewable energy and it is possible to harness electrical energy from people by the use of EGGS. Human energy is wasted when excessive calories of body are burnt during exercise in gymnasiums to achieve the desired fitness. EGGS will provide an opportunity to return expended energy in the form of electrical energy from gymnasium equipment and cardiovascular machines. This electrical energy will be cheap and also green since it will not emit any carbon dioxide (CO 2 ) gas during the process. This system can increase the potential of renewable energy area and the electrical energy generated from EGGS can be sold back to the national utility via micro grids (MG). The proposed system will be very beneficial for such countries that are facing energy crises as well as the third world countries. Authors have discussed a gymnasium machine named as “Pull-down machine†and proposed a theoretical modification to make it as an energy generating gymnasium machine (EGGM) in the presented research.

Highlights
The world around us is changing significantly and the use of technology has become one of the major drivers for economic and social development
In the proposed theoretical model, it is concluded that the expended energy by people during exercise in gymnasium in order to burn their calories to achieve their desired fitness level can be converted and stored in batteries in the form of electrical energy
energy generating gymnasium system (EGGS) are very beneficial for the gymnasium owners, because this system would make the gymnasium independent in the energy production
Summary
The world around us is changing significantly and the use of technology has become one of the major drivers for economic and social development. World net electricity generation increases by 45%, rising from 23.4 trillion kilowatt hours (kWh) in 2015 to 34.0 trillion kWh in 2040 [2]. World net electricity generation increases 69% by 2040, from 21.6 trillion kilowatt hours (kWh) in 2012 to 25.8 trillion kWh in 2020 and 36.5 trillion kWh in 2040. A generator is connected to these machines in such a way as the circular rotation of the front wheel rotates the coils of wires inside the generator between the poles of the magnets [5] These machines generate electricity from their rotating parts, which lead the authors towards an idea of extracting energy from gymnasium machines that do not exhibit rotating motion but have linear moving parts. The process of photosynthesis generates fuel but it releases
