If you are looking to build muscle or strength via a bodybuilding routine, stick to 4-5 sets of 10-12 repetitions. Focus on positive and negative of each movement of each repetition. Gradually increase weight as you work out to force your muscles to work. Otherwise your muscles will become programmed, accustomed to same weight and you will no longer experience any gains. There are many approaches and techniques that can be used in bodybuilding. Experiment and use best one that fits you. An excellent book about weight training and bodybuilding that discusses many different techniques to working out is The Weider System of Bodybuilding.

If you are looking to tone or just stay in shape and be healthy, an exercise program combining weight training and a cardiovascular workout is appropriate for you. When you are exercising with weights, 3-4 sets of 12-15 repetitions at a reasonable weight would be appropriate. Combine this with cardio exercise 1-2 times a week such as riding an exercise bike or elliptical machine or by joining classes at your gym. It is difficult to discuss in great detail in this article exactly what you should be doing. For custom exercise programs I highly recommend Global, Health and Fitness

Here is a sample exercise program that can be modified to fit any person's fitness goals. Remember that you can change order and incorporate different exercises for each body part on weekly basis. I encourage this to prevent boredom and your body getting used to same routine.

Rain, snow, sleet or hail, it doesn't matter because you'll be able to workout anyway!

But wait a minute - there's so many treadmill brands to choose from!

And why are there so many differences of opinion?

If you've read many treadmill reviews in your search for best treadmill you may have ended up a little confused:

One person swears by their Proform treadmill; another says it's a piece of junk. One expert loves Nordic Track; another expert wouldn't touch it with a 10 foot pole.

How are you supposed to make a smart decision with so many conflicting opinions?

To help you out, here are top 3 things to keep in mind when reading treadmill reviews:

#1) Consider this: It's just ONE PERSON'S opinion.

People have different opinions on everything from movies to ice cream to cars to cities. Someone prefers Honda to General Motors. Another person prefers Dell over IBM.

That doesn't mean that one thing is necessarily better than another, it just means somebody has a preference for it.

So just because you really want to buy a Landice and one person may not agree with you doesn't make it a bad buy for you.

Keeping an open mind is always a good thing and listening to other's peoples' reasoning behind their decision can help you with your purchase.

But in end it's your choice and it's YOUR opinion that matters.

Just because somebody doesn't like what you like, that doesn't mean you are going to make a bad decision. If your treadmill has everything YOU need, then that's what's important.
