Questions & Answers

Ask a Question
  • Is this good for a girl wanting to make her pec muscles bigger and stronger?

    Well, yes, it's good for ANYONE who wants to target their chest muscles with high resistance exercise. I would recommend combining power twister usage with push-ups and bench presses (at least) for the best results.

  • Does this have resistance as you pull outward (abduction) as welll as resistance when pushing in (adduction)?

    Thank you interested in our products. There is only a resistance when you pushing in. If you have any problem, please do not hesitate to contact us.

  • Which part of the body can be exercised with this power twister

    This product can effectively exercise our arms, shoulders, neck, and back. It is very practical

  • Is there resistance in both directions??? (out and in?) Thanks!

    No. Resistance "in" only.There is no resistance in the out position.
     It's a hydraulic so nothing pushing outward.

  • What is it made out of?
