Inventor Series: REP® x PÉPIN™ FAST Series™ Adjustable Dumbbell

REP® has innovative minds on our Colorado-based engineering team. At the same time, we sometimes run across other inventors doing awesome things. These are our people. We want to support them. That's why we created the Inventor Series: a special line of products invented by small, outstanding inventors from around the world. We collaborate with the best of the best. And then work closely alongside them to optimize their ideas, using our resources and knowledge of the home gym market. The goal is to simultaneously lift up other gym equipment inventors, while making their amazing products more accessible to more people. It's a win-win-win. The REP® x PÉPIN™ FAST Series™ adjustable dumbbell is a partnership between REP and Canada-based Pépin. 

Meet the REP® x PÉPIN™ FAST Series™ adjustable dumbbell in kilograms. These premier adjustable dumbbells are heavier and more compact than most adjustable dumbbells on the market. An adjustable dumbbell that starts at 42.5kg and can go up to 62.5kg at only 465mm long is pretty much unheard of. All steel, CNC-cut plates with a black powder coating allow the dumbbells to be incredibly compact, very accurate, and look and feel great. In addition, they’re extremely durable. Both the dumbbells and the cradles are constructed entirely of metal (with UHMW liners to prevent steel-on-steel contact) and have been extensively drop-tested from every angle. The steel cradles allow you to rerack the dumbbells without worrying about being overly gentle, as would be the case if the cradles were plastic.

 

 

And it’s quick, easy, safe, and satisfying to change the weight in 5kg increments – with just the press of a magnetic pop-pin. Adjust weight inside or outside the cradles (ideal for drop sets). Or add the included 1.25kg micro-plates for smaller adjustments. Adjustable dumbbells take up a small footprint in your gym, especially when compared with a standard set of dumbbells.

The REP® x PÉPIN dumbbells are offered in 32.5kg, 42.5kg, 52.5kg, or 62.5kg pairs. The 42.5kg pair meets the needs of most lifters but is still upgradeable to the heavier options in the future. The cradle also expands, so no matter the weight, you never need to buy a new cradle; simply unscrew the end pieces and screw them back into the correct, pre-drilled holes. These dumbbells feature high-end details, like nickel-plated handles with volcano-style knurling; functional side rails with comfortable, rounded outside edges; UHMW protective liners to prevent scratches from steel-on-steel contact; laser-etched weight markings (no cheap stickers!); and more. Pro-style heads look and feel like regular dumbbells, but the flat bottom still keeps the dumbbells from rolling on the ground. They’re further elevated with an aesthetic "REP® x PÉPIN" nameplate on the cradle and REP® mountain logo cutouts on the ends of the cradles. Make no compromises. A new bar for the best adjustable dumbbells has been set.

Note: The REP® x PÉPIN™ FAST Series™ is designed exclusively for flat storage and operation, meaning it’s optimized for use on level surfaces. Using it on an angled surfaces, trays, or racks may impact its performance and stability, leading to potential operational issues. See our two official REP adjustable dumbbell storage options to ensure proper securing of the cradles and future compatibility: Dumbbell Storage Cart and REP® Adjustable Dumbbell Storage Stand.

Always ensure the pin is fully engaged before using the weights. The ring should make contact with the pin housing, and the pin shaft should not be visible. Failure to secure the pin properly may result in the weight dislodging, potentially causing injury or equipment damage.

Great Value for a ball my dog loves!
Color: S6-muti-color
I wish these ball were in the subscription program! My dog gets sooo excited by the new ball, but her interest in things lasts for a few days. She kills the squeak within 11minutes, but the squeaker stays in place rather than becoming a chocking or swallow hazard, and she still loves to chew it. Next, we must throw the ball approximately 723 times the first day, possibly 496 times on day 2, and just 3- 4 on day 3, at which point she will chase the ball before hollering "it's over here if you need it," while she checks on the chipmunk den. We currently have 17 of these balls in our yard (because we have given several leftovers to a less discriminating doodle next door). These balls hold up really well, get her extremely active for the first couple of days, and are a much cheaper than doggie daycare (after an active morning with a new ball, she is happy to chew on it and sleep much of the day). I always have these on hand!

Pieces chewed off
Color: white & green
My Aussiedoodle loves it. I throw it down the hallway, it bounces crazy, and he chases it. The only complaint is that he can't chew much of the ball part. So now I have to have it put away and brought out for special playtime.
