You can use them as a reference for yourself. You can also use them to compare them to.
There is a reason why many fitness companies have developed products with an integrated training program. We have all seen and heard of some people who can train for 2 days and not make a single lift. That is not really practical. I have a different method. I go to the gym 3 times a week. I am at a moderate weight for the first time, but I am also training for several different goals. Each workout consists of 10-15 minutes of cardio and then 10-15 minutes of strength training. I usually go for a 10 minute cardio in the morning and then I have some strength training for a little more than an hour. I have also done bodybuilding exercises and I am a very strong man. I can do 1.5 pull-ups, 1.5 dips, 1.5 chin-ups, and 1.5 back raises with ease. I would say that my strength training should be at least 50% of my total body weight, for an hour-long workout. The goal is to get all of your muscles working at full capacity. So, I would say that it is important to have a plan in mind that can keep you motivated throughout the entire process.
