Or

Undo the Velcro on the included wrist strap which was packaged with your other included accessories and insert one side into the wrist strap holder on the center of the handle. Once one side it attached, close the strap using the Velcro. If using the original jogging strap that came with Indie or Indie Twin, lie the strap with equal lengths over the handle and select one side to pull through the other side’s loop and pull taught. Your jogging strap is not attached and ready.
