PowerBlock Pro 100 EXP 40, Knurled review

The knurled 40-pound Pro 100 EXP is the starting pair in PowerBlock's residential 100-pound system. It makes sense when you want a metal grip and expect to buy heavier stages later, while keeping the initial purchase at 40 pounds per hand. The important qualification is that future capacity is a purchasing route. This package does not include the plates needed for 60, 80 or 100 pounds.

What the starting package actually supplies

The current US product selector identifies this as Knurled / 40 LBS, SKU 504-00183-03, sold as a pair. The Pro 100 EXP manual describes the Stage 1 maximum as 40 pounds per dumbbell. Each handle includes two removable 2.5-pound micro weights. With both removed the handle weighs five pounds; with one installed it weighs 7.5 pounds; with both installed it weighs ten pounds.

Those handle adjustments should not be mistaken for a complete ladder of every 2.5-pound value. The published plate selections include 15, 17.5 and 20, then 25, 27.5 and 30. There is a five-pound jump from ten to fifteen. Someone who needs exactly 12.5 pounds should choose a system that actually supplies that selection, rather than infer it from the phrase micro adjustable.

A metal grip with a separate adjustment routine

PowerBlock specifies a 38 mm knurled stainless steel grip with a 4.88-inch grip length for the knurled Pro 100 EXP. That is thicker than the 32 mm grip listed for the Elite USA 50. A purchaser comparing the two should consider hand fit and the feel of the surrounding structure as well as their maximum loads. Knurling describes surface texture; it is not evidence that every hand will find the diameter comfortable.

The magnetic selector pin chooses nested plates. Changing a micro weight is another operation: remove the handle, use its Auto Lock control, change the internal weights and close the lock before lifting. This can suit a planned sequence of sets. It is less convenient when your routine repeatedly needs a small adjustment that also requires handling the micro weights.

Expansion has an exact order

The official sequence adds Stage 2 for 60 pounds, Stage 3 for 80, and Stage 4 for 100. The manual says to install these stages sequentially and states that the Pro 100 EXP expansion kits do not fit other PowerBlock dumbbells. Buying a visually similar used plate set is therefore an identity problem, not an automatic bargain. Keep the model and stage names with any later order.

The 60-pound knurled package is the more direct choice if your present routine already exceeds forty pounds. Conversely, the non-expandable Pro 50 has a different supplied weight ladder and can be more relevant when a fifty-pound ceiling is enough. An upgrade route is useful only when it addresses a real future requirement.

Allow room to select, lift and inspect

The handle must travel straight out of and back into its nest. Twisting it during removal can jam the assembly. Leave space beside the stacks for the pin and room above them for the manual's short lift and visual engagement check. The smaller forty-pound package's exact full-load measurements remain unconfirmed; ask for that stage's dimensions before planning a tight shelf.

Inspect the pin, magnetic contacts, tether and hardware before use. The manual prohibits dropping the dumbbells and striking them together, and specifies gentle cleaning with a microfiber cloth and warm water. A urethane finish does not turn the mechanism into equipment intended for repeated impacts.

Who should choose this configuration?

Choose the forty-pound knurled pair for a modest current load range, a deliberate preference for textured metal, and a credible plan to expand within this exact family. Choose a softer-grip version if that surface matters more, or a complete higher stage if you already need its load. This is the residential Pro 100 EXP; the separate Commercial Pro 100 five-pound-handle recall must not be used to identify an unknown secondhand set by appearance alone. Check the actual model and current manufacturer notice before purchasing used equipment.
