Learn them, and 70% of your battle's already been won. These basics are a must for any serious lifter/athlete to build a basic strength and physique base. Similarly, compound/multi-joint movements are always the "bread and butter" for every good training program – learn them, master them, repeat them, and improve them! Keep in mind that sometimes a workout of 10 sets of heavy deadlifts or squats will give you a better workout than any "fancy" leg/back session.
Training intensely is the key to stimulating muscle growth but don’t mistake volume for intensity. All too often, people trying to achieve a higher level of intensity in their training make the mistake of assuming that increasing volume and duration are effective methods of boosting training intensity. Let me make this perfectly clear. Volume and frequency have absolutely nothing to do with intensity! High volume training sessions can actually be counter-productive. So how do you effectively increase intensity? A. By progressively increasing the amount of weight that you use. B. By progressively decreasing the amount of time it takes you to perform a particular amount of work. (For example, I have made some of my best muscle gains from workouts that lasted no longer than 30 minutes.) C. By working your muscles at the capacity of nothing less than 100% on every set.
To build extra muscle, you need to eat in excess of what you currently eat, and work out with weights on a regular basis. How much muscle you can gain, how quickly and with what definition is largely determined by your genetics and age. But everyone at almost any age should be able to gain some muscle and strength with weight training. Proper nutrition is a crucial element in the muscle building process.
Also, make sure to bring about sufficient variety in your routine once every 2 months or so. These are some generic rules for starters. If you can follow them you should be on the right track. By that time you would have had enough experience or made enough friends in body building who knows the craft better than someone who is not into it but has only a general idea of the proceedings.
(Note that multiplying your bodyweight by 20 results in a high calorie estimate specific to building mass. Many maintenance calorie estimates are closer to body weight multiplied by 15. If the result of multiplying your bodyweight by 20 seems incredibly high given what you know about your body, you can err on the conservative side and multiply by 16-18.)
The snatch is one of the two current olympic weightlifting events (the other being the clean and jerk). The essence of the event is to lift a barbell from the platform to locked arms overhead in a smooth continuous movement. The barbell is pulled as high as the lifter can manage (typically to mid [ chest] height) (the pull) at which point the barbell is flipped overhead. With relatively light weights (as in the "power snatch") locking of the arms may not require rebending the knees. However, as performed in contests, the weight is always heavy enough to demand that the lifter receive the bar in a squatting position, while at the same time flipping the weight so it moves in an arc directly overhead to locked arms. When the lifter is secure in this position, he rises (overhead squat), completing the lift.
For every person who lifts weights these days, it seems there are two who have a podcast about it. There are more bodybuilding tips promising greater strength and muscle than ever before, and along with them a ton of confusion; one buffed-up Instagrammer says lifting heavy will get you swole, while a well-known fitness personality has claimed in recent years that two 30-minute workouts per week netted him 34 pounds of muscle in a month.
