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.

Nice
Size: 16 Fl Oz (Pack of 1), Style: Pawsitively Fresh
It's fine. It works well to mask the scent of whatever you're trying to hide. No residue. I just wish it was a bit more citrus-y.

It works!
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
There is a strong smell or roasted coffee beans but since I started using this product my edges are healthier and the hair at the middle of my head that has been struggling to grow is gaining some length. The product itself can get hard depending on the temperature of your room but if you use it as directed the texture isnt so bad. The oil is thick and not very greasy or difficult to wash away. Definitely effective. 100% will recommend.

It's Working
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
I like how it softens and protect hair. I am using sparingly on my scalp and have not used enough to see hair growth yet. I have had it for a month but do not use daily. I am growing my grey hair out and I have noticed that some of the white hairs are more salt and pepper now so it naturally darkens hair. My friend who told me about the product has been using it longer and her grey hairs are pretty much unnoticed by the natural darkening effect, blending enough to give her a light brown look. I have extremely fine thin fragile hair so I leave it on instead of rinsing or washing it out per instructions, that is another reason I do not use daily on hair and scalp. So far I have not had any negative side effects by using sparingly and leaving in until weekly wash. There is a strong smokey smell but not overwhelming for me and the scent dicipates within an hour or less.so I am not bothered by it. After using product on my hair, I rub a little on my nails & cuticles. It appears to help, as my cuticles are a lot healthier now.

Ash vs. Moisture/Success?
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
The product feels great on the skin and moisturizes well. Although, don't be fooled by the smokey coffee detail. I'm an avid expresso bean grinder and drinker, this is no coffee. Smells like strong chain smokers favorite corner of the house on a stressful day. Imagine ash trays and Jojoba blended. Now that that's explained, it genuinely feels great on the skin/beard/scalp. Unfortunately, I am unsure how long my wife will tolerate this as a nighttime routine.

Strong coffee smell. Might not be be compatible for everyone. However, product is really good.
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
Love this product. May not be compatible for someone who doesn't like smell of coffee that does not detract from the product. it's really good for hair.
