Tough as Nails Meaning
Definition: Strong and stubborn or determined.
This can also sometimes mean rarely ill.
Origin of Tough as Nails
This expression is somewhat ambiguous since a person could use it in either a positive or negative way.
When used as a compliment, it means that a person can handle any problem and keep enduring. When used as an insult, it can mean that a person is unfeeling, cold, or harsh.
Early publications with this expression date back to at least the 1860s. The synonymous expression hard as nails came first, in the early 1800s. For over a hundred years hard as nails was more common. However, modern usage is roughly equal for each idiom.
It is unclear whether the word nails in the expression refers to the metal nails used in building or the body part at the end of the finger. Both ways would seem to make sense.

Kimberly: She was so strict as well. She wouldn’t tolerate any nonsense.

In the second example, two friends are at the gym.
Keira: I just hired a personal trainer! He should be here at any moment to get me started on my workout.
Rory: Are you serious? Was that really necessary? Can’t you workout on your own?
Keira: Um, I could try. But in the past, I always give up too easily. I never push myself. That’s why I hired someone who is tough as nails. This guy is so intense that I know I’ll push myself to my limits!
