Abstract

A weight sled for fitness training that uses a plurality of resistance mechanisms to allow for adjustment of resistance. Depending on the configuration, wheel skid or slippage control may be provided by electronic monitoring of the angular velocity of one or more wheels and electronic adjustment of the resistance of any skidding or slipping wheels, bias correction and directional control may be provided by using a plurality of resistance mechanisms via differential adjustment of the resistance of the plurality of resistance mechanisms, and differential adjustment of the resistance mechanisms may be used to manually or automatically offset a directional bias in the sled, ground surface, or the athlete's abilities to keep the sled moving in a linear motion, and to prevent wheel skid on surfaces with differing friction coefficients.
