Just so we're clear, some folks believe that they can workout in the gym on day one, then go cycling on day two. After all, since they're not training on two consecutive days with weight they're taking the day off right? Wrong! Rest means no training of any kind -- nothing, nada, zip.
As for everybody being different, sure we recover at different rates but all things being equal, that rate is small. In other words, don't neglect rest and recovery. Otherwise, you do more harm than good.
