Fitness Philosophy:

Working out and staying fit has always been a passion of mine. I have played almost every sport and I coached club water polo so I love seeing my team grow to love the sport and what they do everyday and I hope to bring this enjoyment to the students in my class, too. It is so amazing that our body's have the strength to do what they do everyday and that we get to glorify God through this.

 Kassie T

Kassie Terra

Year: Graduate Student
Hometown: Ventura, CA
Major: Teaching Credentials: Multiple Subject and Masters in Science
Areas of Specialization: Zumba, Deep Stretch
Fitness Philosophy: Fitness has been something that has played a major role in my life growing up. Having this opportunity to teach and share what I have learned through classes like Deep Stretch and Zumba, gives me such a unique opportunity to encourage all who come to my classes. I have taught dance for several years now and my desire is that people will come to my classes having the attitude to just do their best while having fun doing it. My classes are about getting up and trying, not about perfection. My hope is to inspire others to find other avenues of working out so that they will not become burnt out and that they are able to enjoy what they are doing.
Favorite Scripture: Matthew 6: 34 says, "Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own." While going to school full time and working at the Recreation Center part-time, this scripture has been one of my favorites for the fact that life is too short to worry about the things in my life that I can’t control but to instead just give it all to God and resting in the fact that He has it all.
