We’re all a little different, physiologically speaking, and some people have longer arms than others. Does it make any difference if you’re working a power training routine? A study published in the Journal of Strength and Conditioning Research suggests that arm length can have an impact on maximal power, and offers suggestions for individualized power training.

Scientists measured the upper arms, forearms, and total arm length of 26 professional rugby players before testing them on a bench press. Peak power was achieved using loads between 20% and 60% of one rep max (1RM), and maximal power was achieved at 30% of 1RM. But for subjects with longer upper arms, maximum power was closer to 22% of 1RM.

True Strength Moment: Adjusting resistance to power train specifically for your build is just another way to take it to the next level with individual differences. If that makes your training more effective, it’s definitely worth the effort.
