Abstract: A resistance supplier for weight training has two switching assemblies, two planetary gear sets, a one-way output bearing, a spindle, and at least one weight. The two switching assemblies respectively control input, output, and fixing of the sun gear, planet carrier, and ring gear in the two planetary gear sets. The output of one of the two planetary gear sets is used as the input of the other planetary gear set. Therefore, the two planetary gear sets provide three reduction ratios and transmit torque to the spindle through the one-way output bearing to drive the weight to rotate. By using reduction ratios of the planetary gear sets to increase the output requirement of the user and switching gears via switching assemblies to change reduction ratios, the resistance supplier can provide sufficient and diverse training resistances with a single weight, thereby reducing the volume.

Abstract: A dumbbell with detachable weights has a handle assembly, multiple weights, a first end cap assembly, and a second end cap assembly. The handle assembly has a main support with a handle, a first end panel, and a second end panel. The weights are mounted between the first and second end panels of the main support, are arranged around the handle, and are radially detachable from the main support. The first and second end cap assemblies are respectively mounted on the first and second end panels and selectively engage with the weights. By turning a driving cap of the first end cap assembly, the first and second end cap assemblies can disengage from the weights. Since the weights can be radially mounted onto or detached from the main support, an adjusting range of the training weight of the dumbbell can be increased.
