A pedal-type exerciser includes a base, first and second drive assemblies, a transmission chain, a pair of elongate pedal members and an elastic cord unit. The base has front and rear end portions. The first drive assembly has a first horizontal axle mounted rotatably on the front end portion of the base, a first drive wheel mounted securely on the first horizontal axle, and a pair of first crank arms mounted securely on opposite ends of the first horizontal axle. The second drive assembly has a second horizontal axle mounted rotatably on the rear end portion of the base and horizontally spaced from the first horizontal axle, a second drive wheel mounted securely on the second horizontal axle, and a pair of second crank arms mounted securely on opposite ends of the second horizontal axle. The transmission chain is trained on the first and second drive wheels. Each of the elongate pedal members is mounted to a corresponding one of the first crank arms and a corresponding one of the second crank arms for moving with the first and second crank arms. The elastic cord unit is secured to the base and is connected to the pedal members for providing resistance to pedaling of the pedal members.
