A system, device and method for fitness tracking include one or more insoles, the one or more insoles having embedded therein a plurality of sensors; a computer having a processor and memory; and one or more code sets stored in the memory and executing by the processor, which, when executed, configure the processor to: receive, as inputs, data collected from the plurality of sensors embedded in the one or more insoles; filter the data; execute an evolutionary algorithm on the data, wherein the evolutionary algorithm converges the data from the plurality of sensors; and determine, based on the converged data, a total weight applied to the one or more insoles.
