One workout for each body part. One for chest, back, delts, legs, abs and arms. None of the workouts take longer than 20 minutes. Twenty minutes is plenty when you have a lot going on with your day. There are some things you need to understand before you go through with these sessions. Don't Waste Time At The Gym: If you spend your precious moments in the gym socializing, then you are not benefiting from these at all. Say "hi" and train. As soon as you are done, get out and go on about your day. Be Prepared Beforehand: Keep your gear or gym bag in the car, have a water bottle full before you leave the house, and make sure you have a shake or food with you so you can eat and begin recovery as soon as you leave. Do Not Rely On These As A Regular Workout Plan: Although they are great for the situations we have already covered, I do not advise them as a regular training plan. Each of these routines has 30 seconds of rest in between sets. There are drop sets, supersets, giant sets and training to failure involved.
