That's pretty much what I did but the problem is that researching things on the internet generally works like this: article 1 says you should lift high weight, low rep article 2 says low weigh, high rep, article 3 says do 800 squats a day or you will catch AIDS.
That's all good, maybe you are just missing a little info in those articles ... Finding an appropriate rep scheme just depends on what you want to accomplish.
If your goal is to be as strong as you can then lower reps / higher weight are good. Powerlifters are in this category and generally don't do more than 5 reps on the primary movements with 3 reps per set being the 'sweet spot' for building strength. At 3 reps per set you won't be building mass as fast as possible but your body will be learning to recruit a larger percentage of the muscle fibers it does have. Sometimes Powerlifters will switch to the other scheme in order to build their mass up.
If your goal is body tone and weight control then lower weight / higher reps is key. Crossfit junkies kind of fit into this class but can fit into the previous class too. Body builders push this even further than Crossfitters.Generally speaking, the higher the reps, the better the mass building. Sometimes Crossfitters and body builders will switch to the other scheme in order to build their strength up.
