Pro 100 EXP

Pro 100 EXP

The Pro 100 EXP is designed to be the last dumbbell you'll ever need. Perfect for advanced lifters, this adjustable dumbbell can expand up to 100 lbs with the addition of expansion stages (Stages 2-4). Start with the base dumbbells and increase weight in 2.5 lb to 5 lb increments, thanks to the included micro weights. Whether you are looking to build strength while maintaining proper form or engage in micro-loading, the Pro 100 EXP is your go-to tool for progressive training. Optimized for compactness, this system reduces the space needed for multiple traditional dumbbells. The magnetic selector pin allows for quick weight changes, so you can transition between exercises with ease.

I’ve used powerblocks in one form or another for the past 15 years, and have almost zero complaints. The upkeep is minimal, you can change weights in seconds, and they take up almost no space. There’s a very slight rattle at times, but it’s never bothered me. The only thing I don’t like is how you have to remove the handle to take out the 5lb weight pins if you want to go up by anything other than 10lb increments. It only takes a few seconds, but I’m just lazy. I really wish I could get a 2.5lb magnet to stick to the urethane exterior, and solve the problem.

Better than the rep peppins in my opinion, great ecosystem to be more modular.

These things deserve so much more love than they get. I can change weights from 10-100 pounds in about 15 seconds! They are quiet compared to their metal counterparts, they are cheaper compared to their more popular counterparts, and they are in basically every strength/conditioning facility across the country so they are doing something right! I want them to get more love so hopefully it'll be a matter of time before people start choosing alternative to the Rep/Pepins.

I technically have the Pro 90s which are slightly smaller than these and 'discontinued' but the concept is the same. I use these for heavy DB work because I have a fixed 5-50 set. They're also a back up second set of DBs if someone is working out with me and we need the same weights. They're durable, simple, and the right level of 'retro' for me to love them. If I was going to have one set of dumbbells, I'd do something different. But with a fixed 5-50 set, these are a great value and option for heavies or secondaries. I also have the kettlebell handle which makes for nice farmers carries (not KB work). BUT the powerblock adjustable kettlebell is great, it's a precurser to what Freak Athlete developed.
