Kim Martin knew her weight was taking a toll on her health.
She's lost 100 pounds over the last 3 years.

She also quit her corporate job and opened her own fitness studio.
It wasn't easy, but she says never gave up.

"When I first started I was so overweight that all I could do was walk. Everything else was so difficult for me," said Kim Martin.
"I just started walking. I walked just a few blocks, sat down, took a break, got back up walked back to my car. But I did it the next day and the next day after that and I didn't quit," Martin said.
"I'm still here today because I haven't quit," she added.

Her studio, Total Body Infusion is opening another location at 56th Street and Old Cheney Road in Lincoln on July 15th.
