Arm, the category that embodies strength and power, is all about building and toning those muscles attached to your limbs that help you carry your daily grinds with ease. It's a hub for trends that involve everything from squat belts that add resistance during workouts to subcutaneous injections that target the deeper layers of fat in the arm. The trends within this category seem to be split between functionality and aesthetics, with some trends focusing on keeping your arms healthy and energized, while others prioritizing cosmetic enhancements. Some of the most popular trends involve innovative approaches to classic exercises, like bicep curls and hammer curls, and using technology to keep track of your fitness journey, like glucose monitors. Ultimately, Arm caters to those who want to feel strong and confident in their daily lives, whether that's by improving their athletic performance or feeling comfortable in their own skin.
