For this CAS experience, I would like to participate in a fitness-kind activity which I will be specifically focusing on core muscle training in this experience. In order to accomplish it effectively, I went to a gym and use mechanical types of equipment that help to specifically improve core muscles with more efficiency. I planned a set of training lists ahead of time which I will be doing 5 mechanical types of equipment to improve core muscles. The equipment I used is for example “SBE”, “abdominal crunch”, and “V-Crunch”. Usually, I did 15 times in a set and I will be doing 3 set for each equipment. I decided to pursue better core muscles because I had taken a body test and it shows that my core is weaker than other muscles such as legs or chest, therefore, I attempt to use this CAS experience to act as a motivation to go to the gym and improve on something I am weaker at. Thus, I will have better performance while doing ball-related sports in the future.
