1.0x
Current: 1.0x resistance

How It Works

  • Start at 1.0x - barely noticeable, like holding a slightly heavier phone
  • Progress automatically as your grip strengthens over weeks
  • Each level adds micro-weights you can't see but your muscles feel
  • Reach 5.0x and your phone becomes a 2.5lb functional weight
