The 100 Workouts Book is for everyone who wants to stay active, get fit, build muscle tone and/or shed extra weight in the home environment without acquiring any extra equipment. Different workouts, some are more challenging and some are easier than others, will ensure that your muscles don't get used to the same regime, giving you more in return, and also help you stay active and not get bored with the same routine. Visual routines are designed to guide you through the workout, as you go from one exercise to the next, in an easier fashion than in a video. Just follow the routine and have fun You don't have to work through the entire book; you can pick the workouts you like most or randomly select one and make it a workout of the day. Ideally you want to do 3-4 workouts per week.
