Daisy CastanedaDaisy Castaneda, ACSM Certified Personal Trainer

My personal philosophy about physical activity is that one’s health and well being should be a top priority. Individuals who are healthier are more likely to have the strength to overcome any obstacle in their lifetime. A healthy and active lifestyle gives individuals the strength and an open mind to resolve conflicts in their everyday lives in the best way possible. Physical activity is for everyone, health and the feeling of well-being is for everyone. A healthy lifestyle shouldn’t be sold but rather taught because it requires knowledge and a motivated body to want to change their ways for the better. A healthy and active lifestyle is not an expensive product in a bottle that can be bought; the cost is more than that because it requires a yearning desire for change that only comes from within. My belief is that an active lifestyle leads to good health and good health leads to happiness, therefore physical activity leads the way to happiness.

As an intern with ACC Exercise Health Sciences Program, it is my objective to provide the knowledge, and perform the art of fitness to motivate and guide the learners become lifetime movers and help them adopt physical activity in their everyday lives. Everyone is capable of becoming a lifetime mover and my job is to set a path designed to help them become one.

Jackson TalleyJackson Talley, ACSM Certified Personal Trainer

My personal philosophy about physical activity is that it should be part of our daily routines in order to optimize physical and psychological health. Through exercise we can reach our goals of increasing physical performance, improve physique, and avoid disease. I believe physical activity can be modified to benefit any individual dealing with physical limitations, lack of time, perceived inability, or inexperience. Every individual will see reward for the time they spend and effort they put towards their goals. Most importantly, physical activity should be enjoyable. Finding an activity that is fun and keeping a positive mindset can provide us with a healthy environment for change.

As an intern with ACC Exercise Health Sciences Program, it is my objective to apply my knowledge as a personal trainer to the students and staff of the college as I continue learning from my peers and fellow staff members of ACC.

Pedro MuroPedro Muro, ACSM CPT

My personal philosophy about physical activity is that we all have 24 hours in a day, and I believe that what we do with those hours is what defines and shapes each individual. We may have all been born in different scenarios and we may face different adversities, but what we decide to build out of our lives and the way we choose to confront our obstacles is what determines the person we will be. I look at the glass of water as half full rather than seeing it as half empty. By having a positive mentality you set yourself up for success. It is always better to exercise for ten minutes than for no minutes at all. Many times, we make excuses to not do something, simply because we are afraid to take a single step without even considering where that first step might take us. For me, exercising is a vital part of my life. I want to be a person who can be an example to follow and someone people can look up to. You should always be the reason someone out there is smiling.

As an intern with ACC Exercise Health Sciences Program, it is my objective to learn as much information about the career I love. It is to absorb as much knowledge and learn from my mistakes. It is to demonstrate the abilities I have learned throughout this program and gain confidence in the work I do.

I am certified with the American College of Sports Medicine as a Personal Trainer. I am more than happy to help and guide you to a healthier lifestyle while giving you support and guidance.
