A variable training resistance device for an in-line skate. The skate includes a boot and a plurality of wheels disposed on a chassis. A resistance assembly, including a cam and bearing assembly or a rack and pinion assembly, is disposed between two of the wheels on the chassis. The cam and bearing assembly includes a plurality of cam carrier blocks disposed along either side of the chassis, wherein one of the cam carrier blocks has a first cam axle fixedly disposed thereon. A cam lever having a second cam axle is rotatably mounted on the chassis, and a plurality of cams are rotatably disposed on the first and second cam axles. Bearings are rotatably disposed between the cams and can be adjusted vertically to contact and provide resistance to the wheels of the in-line skate. The resistance assembly also includes a microadjust assembly to vary the position of the bearings with respect to the wheels of the skate. The rack and pinion assembly includes a rack, a pinion for engaging the rack, bearings disposed about the pinion, and a lever for moving the pinion upwardly or downwardly on the rack. The bearings can be moved downwardly to frictionally engage and provide resistance to the wheels of the in-line skate.
