VIDEO: A former volunteer firefighter from Long Island just won big on ABC's "Shark Tank" for her new fitness device, which was inspired by her time as a firefighter.
Sarah Apgar, of Port Washington, is the creator of Fitfighter and the Steel Hose.
When Apgar joined the Halesite Volunteer Fire Department in 2012, she noticed the firehouse didn't have a structured strength training program. Apgar served as a platoon commander in Iraq with the U.S. Army, so she was familiar with regimented strength and weight training programs.
She began using firehoses around the firehouse to train her colleagues.
Throughout the next few years, Apgar began developing a fitness device based upon the firehose. She used real firehose material and filled it with recycled steel shot. She called it the Steel Hose.
The longer the hose, the heavier it is. They range in weight from 5 pounds to 50 pounds.
