I never said to do endless pumping. You can accomplish exactly what you are pushing using about 70 percent of your 1rm with different methods than loading up the bar every time you work out. Supersets is one of the may ways to do it. You can grow a million different ways, and a smart trainer uses all methods.
For example, your pec muscle has no idea that it's benching 300 lbs. It knows that it needs to increase in size to move that weight for a certain amount of reps. If you can only get 4 reps with 300 lb's and you attempt to get 4 reps with 305 lbs the next week, thats when injuries occur. At an advanced stage, you are not going to put on muscle quickly. I could bench my 300 one week, and then work with dumbells for 5 sets of 12 hard reps (with great form) the next week. The week after that, I bench my 300 with a slight incline and go for a few more reps, then I follow that up the next week on a hammer strength machine doing drop sets till failure. It's all about shocking the muscles, and increasing weight is one of the MANY ways to do it. You can stress your muscles in many different ways, and they will have no idea about what kind of weight you are using, just that they needs to grow to accompany whatever stress you have put on it to make it fail.
I have seen skinny geeks with massive calves - ( better than a lot of bb's) who sit on the stair climber for two hours a day. They dont increase their weight every week, and if they did their calves would not grow and grow until they where 21 inches. Ob i'm not saying you should work with light weight all day long, but your method is far from the only way to train.
bullshit.
1. stop putting words in my mouth. i never claimed that strength increases is the only avenue for growth. BUT its by far the most important.
2. second paragraph is bullshit. the muscle knows tension. and increased tension is the main trigger for growth. shocking the muscles is pure bullshit. also, changing too many factors from workout to workout makes charting progress very difficult. and alot of people get lost with that kind of set up. they vary their workouts so much that they are never adding weights to the bar. = ONE OF THE MOST FREQUENT MISTAKES THAT LIFTERS MAKE.
3. third paragraph: if skinny guy with big calves wants his calves to grow he gotta use heavier and heavier weights. dont compare person A to B. its about strength increases, not relative strength.
finally ;yes, there are other ways to grow: you can increase volume to some degree to get some growth, you can lift more lbs per time unit (supersets, dropsets...less resting time between sets etc) but all these methods are secondary to strength increases as means for growth.
and obviously no one will be able to add weights every workout (unless your a complete newbie). dont know why you think im trying to say that. you have to use common sense.
