EL PASO, Texas (KVIA) -- Sarah Zambrano is the epitome of strength and determination. She's a crossfit competitor, a runner, and a mother of two.

Her mental strength is to be admired, as she pushes forward to live her best life - for herself, and her family.

EL PASO, Texas (KVIA) -- One of every four Americans is a caregiver to someone 18 years or older. That number has risen 45% in the past decade - nearly 20 million more caregivers than in 2015. According to AARP, this population includes unpaid family members and paid family members. It's called "the invisible workforce," and it can take a toll.
