PowerBlock Elite EXP 70-90 lb. Dumbbell Kit, Stage 3 Expansion Kit, Only Compatible After Stage 2 Adjustable Dumbbell Purchase, Durable Steel, Innovative Workout Equipment Black

I’m doing my workouts with an online trainer at TrainWell (highly recommended them). I do my workouts at home where room is at a premium. So I had the 50 lb blocks. When my trainer said I was ready to move to 60 lbs, these were easy to get and extend my blocks. These extended weights are easy to place with core system and because of the size is small enough I store them in a closet. I do my workouts outside in Florida, so hot, humid, salty, rainy environment, and they are still holding up great. I have been using the Power Blocks EXP for almost 2 years. The weight steps are great. Even the grips as still holding up.

Not much to say, they work as expected. The fit my powerblocks exp that I got from amazon. Very helpful for progressive overloading.

I’ve owned many adjustable dumbbells and the power blocks are by far my favorite system. They are sturdy and simple.

Perfect. I love these powerblock weights. They make storing up to 90 lbs so easy. The adjustment is easy and intuitive once you use them a few times. I don't drop them or throw them, but they seem like they would hold up to a good amount of tossing around. The form and function are perfect for a home gym.

fits perfect

For my dumbells perfectly and have lasted for the vet year. Make sure you have compatible dumbells as some won’t allow for these expansion packs.

I think these are a newer version and are slightly larger than my older version handles. Still gets the job done!

Grips are great, perfect dumbbell size. Weight is accurate.
