An exercise wheel comprises a housing, two grip rods respectively secured to two sides of the housing, a chassis housed by the housing, a main shaft supported by the chassis, a main gear mounted around the main shaft, two wheel assemblies, and two torsion springs. Each wheel assembly is rotatably mounted to the chassis and includes a shaft with a toothed portion for meshing with the main gear. The torsion springs are mounted around the main shaft and respectively located on both sides of the main gear. Each torsion spring includes a first end securely attached to the housing and a second end securely attached to the main gear. The main gear comprises a peripheral stop surrounding at least one of the torsion springs to thereby avoid radial outward expansion of the torsion springs resulting from movements of the wheel assemblies in a rearward direction.
