A training apparatus for training a user's grip and strength. A rod element is disposed through a female tube that is disposed at a first end of the rod. The rod extends through a male tube that is inserted into at least a portion of the female tube. A grommet is disposed on the rod, inside the female tube, and abutting the male tube. A fastening means couple to the first end of the rod, mitigating movement of the grommet toward the first end. A tensioner is rotatably attached to a second end of the rod, wherein when the tensioner is rotated clockwise it presses the male tube forward against the grommet, which is compressed between the male tube and fastening means, expanding inside the female tube. The grommet pressing against the inside of the female tube provides a desired resistance for a user rotating an attached training member.
