Norm Devio is an arm wrestler whose career can be measured in years (40), national titles (25), or trophies (500+). And the 76-year-old isn't done yet.

"While Devio is very passionate about arm wrestling, he is also a family man, and loves to spend time with his wife, Beverley, and his kids and grandchildren," said Boston photographer Adam Glanzman, who documented the retired school gym teacher in the spring of 2016.

In the 1980s and '90s, Devio was such a formidable competitor that he could succeed in any weight class. Devio and some of his peers were even called upon to teach Sylvester Stallone arm-wrestling techniques for the actor's 1987 arm-wrestling movie Over the Top.

These days, Devio — fondly nicknamed by some as "Mr. Rope Veins" — stays meticulously on top of his game. He exercises every day in his Massachusetts home — doing chin-ups, pull-ups, and press-ups — and every Thursday night he meets up with local arm wrestlers to work on technique. When he competes, he can still send chills down an opponent's spine.

Take a look at this mighty competitor in action:
