There was this story about an anorexic / disabled guy that had no strength what-so-ever, but when he got summoned, he placed all of his points into strength.

Got a trait/perk/skill called All in- Strength that disabled the training limit, but only allowed him to put points into strength.

Afterwords, he does general isekai stuff until he lucks upon one of the expensive services of a priest for free by saving a trainee/daughter, getting his original disease healed.

Has rising strength gains afterword.
