Like in most training videos, you see them doing lots of warmup sets ramping up in weight each set to do maybe only 1 working set to near failure, sometimes 2. I don't get it? I don't see how that's training hard.
They do what is needed to grow, and not more than that.
What many people forget that atleast in bodybuilding it is an endurance sport. The person who can train the most for the longest (in combination with a drug regime) is likely to [eventually] build the most muscle. There is no point in rushing through a warm-up and moving big poundages when you can do it once/twice a week for several years before you need multiple hip replacements and have multiple fuzed vertebrates. Meanwhile the guy who trains 'smart' and is able to continuesly train and hit various musclegroups continues to grow.
Compared to topsports-athletes (bodybuilding is not a topsport) bodybuilders have a much longer-timeframe in which they can become succesful before they go over the hill. Being able to train consistently for many years is preferable to inflicting short/long-term damages which may prevent training for short/long periods. E.g. a (pro)bodybuilder who is out due to an injury for 2 years whereas his competitors are not, is unlikely to be able to compete with said competitors 2 years later after rehab. Which is not to say he cannot build muscle, but comparatively he'll have reduced his time to grow.
The implications for the average gymrat:
Unless you actually have a shot at getting anywhere competitively [national/international top] there is no point to lift big poundages and risk injuries (or to heavy dose for that matter). Better to go for the fabled 'health-look', and by that I don't mean the healthy purple glow.
