PowerBlock sets use a block shape with a pin that sets the weight. The blocks stay compact and the frame feels solid to many owners. Changing weight takes a few seconds, which is slower than a dial, but the design is known for being durable. Some people find the square shape uncomfortable on certain exercises.

Who it is for: lifters who want a sturdy set that fits in a small footprint.

• Pros: compact, strong reputation for durability, expandable on some models.
• Cons: the block shape can feel odd for some moves, and pin changes are not instant.

Verdict: a dependable long-term pick.
