What reviewers reported

  • The creator compares this hydraulic piston design favorably to old spring-loaded power twisters, noting the spring versions could pop back out and were more dangerous, while this one is safer.

    Comparison · design

  • The device includes a built-in rep counter that increments automatically each time the arms are pushed together and released, as demonstrated going from 11 to 12 reps.

    Creator experience · design

  • The device can be flipped/repositioned so that pushing the arms one way targets the pecs and arm muscles, while placing it behind the back targets the back muscles.

    Creator experience · design

  • The resistance dial is adjustable by twisting and increases in increments of two, ranging up to 20.

    Measured · design

  • Setting 1-4 corresponds to about 22 lb, setting 4-8 corresponds to 86-176 lb, and setting 16-20 corresponds to 352-440 lb

    Measured · performance

  • One creator said they tried doing curls with the hydraulic power twister but found the movement a little awkward and that it seems designed for one specific pressing motion rather than general exercises.
