## Abstract

Disclosed is a swimming exerciser mainly including a main frame, a pair of pedal means pivotally connected to two rear ends of the main frame, an height-adjustable abdomen cushion connected to a front top of the main frame, a front telescopic tubular support angularly and pivotally connected to and in front of the main frame, and a damping-type grip means mounted on a top of the telescopic tubular support. The grip means, the abdomen cushion and the pedal means together form an angle-adjustable inclined plane suitable for a user to train his or her body through imitative swimming movements.

## Claims

### Claim 1

A swimming exerciser for users to train their body through imitative swimming movements, comprising a main frame, a pair of pedal means, an abdomen cushion, a front telescopic tubular support, and a grip means;
said main frame including two lateral substantially horizontally extended protective rails and a slightly angularly upward extended front middle stem;
said pair of pedal means each including a substantially vertically extended link pivotally connected at an upper end to a rear inner side of one of said protective rails of said main frame, and a pedal pivotally connected to a lower end of said link;
said abdomen cushion being connected to a front joint of said two protective rails with an adjustable distance left between said abdomen cushion and said protective rails;
said front telescopic tubular support being pivotally and angularly connected at a lower end to a front lower portion of said front middle stem of said main frame and further including an outer section and an inner section slidable up and down within said outer section; and
said grip means being mounted to a top end of said front telescopic tubular support and including a pair of pulleys located at two sides of said front telescopic tubular support, an elastic strap being locked at a middle point to a height-adjustable retaining means on said inner section of
said telescopic tubular support with two ends passing through said pair of pulleys, and a pair of hand grips connected to two ends of said elastic strap;
whereby said grip means, said abdomen cushion and said pedal means together form an angle-adjustable inclined plane on said swimming exerciser for best training a user through imitative swimming movements.
