Strength without control is meaningless in constructive weight-training.
Weight-lifting should be the means, weight-training the end and not the other way around.
Avoid over-training in sets and reps and adopt the strategy of intensity.
The more weight you can lift in any given exercise the more inferior it is to its counterpart where the degree of lifting difficulty is greater.
Your muscles grow while you are resting, not while you are training.
All other factors being equal, your genetics will be the determining factor influencing the kind of physique you eventually produce.
Whatever your goals or objectives treat weight training like a journey, however short or long. It is not a race.
Weight training sessions lasting no more than 60-90 mins are more conducive to muscle hypertrophy than long drawn out sessions which may inhibit your recovery time.
Basic compound movements are best suited (especially to beginners) for packing on muscular size.
The degree of stress brought to bear on a particular muscle group is directly proportional to the muscle group's response to the resistance inflicted upon it. Also for a muscle to grow it needs to be stressed, then fed, then rested.
