This verb is derived from an accomplished New York City fitness trainer, Alma. The word is a verb that means to perform a fitness skill at the highest caliber and strength level possible, while still maintaining proper form. This might include the addition of heavy weights to a skill normally performed with body weight only or mastering a skill like a push up balancing on one foot.
Once the student athlete had mastered a basic push up, they almaized the skill and performed it balancing on one leg.
