Are these errors holding you back? Part 2

Last week, I discussed some errors that I see others doing in their training programs as well as errors that I have done before. To recap:
Error 1- Too much wasted time
Error 2- Not performing enough weight training
Error 3- Rest periods are too long
Error 4- Too much training on machines

Error 5- Training on the Elliptical Machine
I've got more. Are you ready?

Error 6- Too much emphasis on body building routines
There is way too much isolating muscles for it to have any benefit. Those looking to get 'ripped' or toned are looking to bodybuilding routines they find in muscle magazines. In reality, those programs will ONLY work if you have the genetics, have done the foundational training to get in shape first, and you perform weight training for a living (you will have to because the programs will take you 2 hours or more).
Solution- Choose exercises that are going to challenge large muscle groups and movements. Exercises such as squats, deadlifts, and other complex moves will yield results for us 'regular folk' in a much faster time than a day of biceps, followed by a day of back, etc.

Error 7- Using the squat rack for barbell curls
Ok, this kind of tags on to number six, but I'd like to expand on this point. Every day I go to the gym, without fail, I see someone performing bicep curls whether on the squat rack or somewhere else. And I can understand that having 'big arms' for the guys is important to their egos, and having toned arms is important for the gals. But there are much quicker more effective ways to get there.
The body works as a unit as do muscles. One muscle never works by itself, performing exercises such as pull ups or rows will involve the arms and will result in defined arm muscles. But will ALSO result in better looking back and shoulders. Don't get me wrong, arm exercises have their place, but should not be the focus of a program.

Error 8- Insane training
Doing the same program over and over again, for months and expecting a different result. The current gym I go to I have been a member for over 3 years now, and there are people in there doing the same exact things they were doing when I first joined!
Solution- Change your workouts every 4-6 weeks. Your body gets used to the challenges placed on it by that point. After that you begin to hit a plateau where you continue to do the same exercises and load with no results. Why should your body adjust to a load that doesn't change?

Training with a purpose using large muscle groups with mostly free weights (or bodyweight), strategic rest periods, and staying away from the elliptical machine and body building routines is really the moral of the story here. If you think of training with large muscle groups for the most bang for your buck (back, legs, chest and shoulders), and how you can train more than one at a time, you will see your results skyrocket, I will guarantee that.
