Adjustable U-Arm Twister Arm Trainer

I bought this thinking it would just be a light travel companion for days I can’t get to the gym, but it’s turned into my go-to upper body trainer. The resistance settings are no joke—even at 60 pounds, you’ll feel the burn. It comes apart so easily that I can toss it into a backpack, and it reassembles in under a minute. I’ve used it in hotel rooms, in the park, and even during lunch breaks in my car (yes, it’s possible). For something so portable, it really works all the major muscle groups—chest, arms, back, and core—without feeling flimsy or gimmicky.

I’ve been traveling a lot lately for work, and I needed something I could bring with me that wouldn’t just collect dust in my suitcase. This Merach chest trainer surprised me—when it’s taken apart, it barely takes up more space than a pair of shoes, but once assembled, it feels like serious gym equipment. The steel spring core gives smooth, consistent resistance, and the foam grips make longer sessions comfortable. I use it in hotel rooms, in my backyard, and even at my desk when I need a break from the screen. It’s rare to find something portable that doesn’t compromise on build quality or workout intensity, but this one nailed it.

Well made and functional.

Simple but gets the job done.
