Brenda Osberg

Brenda has been an avid exerciser her entire life. She took her first spin class at Summit Fitness 8 years ago and loved the awesome workout it provided. She became certified herself as a spinning instructor in 2006 and has been an instructor at Summit Fitness ever since, usually found starting off the workday mornings for the 6 a.m. spinners.

Hello, My name is Josh. I’ve been teaching Advanced Cycle at my local YMCA for the past 8 years and am excited to join Summit Fitness. I am a certified cycle instructor through Schwin. I have been a cross country coach, personal trainer, and boot camp instructor as well.

I have been involved in various forms of fitness for many years, but my true passion is long distance running. I have competed from every distance from the mile through multi-day competition. I have run more than 65 marathons and ultra-marathon during my time as a runner and have been competing in the sport since 1983 in various forms.

I have run the Boston and New York marathon and enjoy pushing myself to the limits of endurance. I have a marathon PR of 2:47:48 and a half marathon PR of 1:16:02. Over the past 11 years I have been involved in Ultra-marathons. I really enjoy the work an effort it take to see how far and fast I can run.

2013 was my breakout year and I won the 3 Days at the Fair 48 Race with 202 miles. This got me the invite to world championships in 2014 for 6 Day running at “The Dome” in Alaska which I placed 3rd with 465 miles and 2nd American.

In 2015 I won the 3 Days at the Fair 72 Race with 293 miles beating the existing course record by 17 miles. In the September of 2015 I went to 24 Hour National Championships in Ohio and placed 4th with 128.5 miles.

I look forward to new races and challenges in competition ahead and hope to bring something new to Summit Fitness.

Allie Insco

My real inspiration to become a group fitness instructor was my mother, Julie White. From the time I was a child, she taught various formats of group fitness classes. It wasn't until after high school that I become physically active. After gaining weight as a result of living an unhealthy lifestyle, I decided to attend my mom's Zumba class. I fell in love with fitness and becoming healthy. I graduated West Chester University with a Bachelors in Nutrition and Dietetics. I am currently certified in multiple group fitness formats including Les Mills, CXWorx, Zumba, Body Pump, Interval Format, Beachbody INSANITY and Beachbody Turbo-Kick.
