Meet the Coaches




Chris Estridge is the owner, operator and head coach at EDGE Fitness & Strength. Growing up very much involved in multiple sports, his passion for strength and fitness training really took off when he first stepped into the weight room at Ben Davis High School. Under the watchful eye of a renowned NSCA Strength and Conditioning Coach, Chris absorbed all that he could at the high school level. He continued to gain experience training others all the while pursuing his Bachelor’s of Science Degree in Exercise Science at Ball State University.

Upon graduation in 2012, Chris went on to become the head coach at CrossFit BLAST Fitness in Indianapolis. Due to unforeseen circumstances, BLAST’s gym owners decided to shut down the business. With many of its core members still interested in training with Chris, he took that as motivation to open EDGE Fitness & Strength in March of 2013 with the help of his sister. Chris has always had a passion for helping others. That fact now comes to fruition as he and the EDGE Fitness staff are able to help changes peoples’ lives for the better through fitness and strength training. There is nothing more gratifying for Chris than to see one of his members achieve a new personal record, lose “X” pounds, drop multiple pant or dress sizes, or to literally hear them say, “You have changed my life forever!”


Chris is married to his beautiful wife, Mackenzie. She, in fact, owns a small business of her own– Younique Culture— a boutique located in Plainfield, IN. Together, they have a dog-child, Evie. When they aren’t managing their businesses, Chris and Mackenzie enjoy spending quality time with friends and family, watching movies, attending concerts, canoeing, shopping, and traveling when possible.

Favorite Quote:
“But He said to me, ‘My grace is sufficient for you, for my power is made perfect in weakness.’ Therefore, I will boast all the more gladly about my weaknesses so that Christ’s power may rest on me. That is why, for Christ’s sake, I delight in weaknesses, in insults, in hardships, in persecutions, in difficulties. For when I am weak, then I am strong.” 2 Corinthians 12:9-10

“What school has taught me about the human body, the barbell has taught me just as much about life. More than just the law of gravity, it can teach us to be just as strong outside of the gym as we are inside of it.”

I am was born and raised in Crawfordsville Indiana. I was a multi-sport athlete at Hanover College as part of the soccer and golf teams. I transferred to IUPUI where I completed a Bachelor of Science Degree in Fitness Management, with a minor in business. I am currently pursuing my Master of Science Degree in Clinical Exercise Science at IUPUI, and expect to graduate in May. I was a Sports Performance intern at Purdue University, working with the Women’s Soccer, Men’s and Women’s Swimming, and Men’s and Women’s Track and Field Athletes. I am an ACSM Certified Personal Trainer. The thing I enjoy most about training people is seeing them get results, whether it be losing a few pounds or hitting a new PR. That’s what keeps me motivated to grow as a coach.

Things I Am Passionate About:  I really like the powerlifting movements (back squat,bench press, deadlift, and standing press) along with a few weightlifting movements such as the front squat and the clean and jerk.  But if I had to choose my top two, they’d be the back squat and the deadlift.  I’m really trying to get stronger at those lifts.

Above all my number one passion lies with my family; I will always be a husband and a father before anything else.

After participating in sports for about 18 years of my life I have met so many people and created some life long bonds. One strong bond was with my high school Defensive Back/Strength Coach who played a major role in me becoming a Coach.


He always pushed me to prepared for the unknown. So I trained as hard as I could and because of this I received a scholarships to Indiana St. University to play football. Individuals who train with me will be challenged in a fun and effective way that allows you to hit your fitness goals.
