If you cannot dedicate an hour three times per week because it is just a lot of time out of your day or it is too costly, then try doing personal training sessions for 30 minutes. You will still get the same results, but in less time. The one thing you need to realize is that the personal training sessions will be less time, they will cost less money, but they will be more intense if you have a good fitness base. If you are just a novice, then the rest times and intensity of your personal training program will start out so you can learn the basics of weight lifting form, breathing technique, and the correct exercises. When you have developed this, the personal trainer can start to design another fitness program that will start gearing you towards your next health and fitness goals. When your form, technique and awareness of your body starts to come together, then and only then will the personal trainer change your program design, increase the workout intensity and alter your cardio/aerobic conditioning. Having a professional Portland personal trainer can help you achieve your results a lot faster instead of doing it on your own, because there will be a blue print of where you are at, what we need to do, in order to get you where you need to go for those awesome fitness results. So, go out and hire a personal trainer for 30 minutes, it will be money well spent!
