I am trying to build a good amount of knowledge and if I can build that then I will progress as I know what im doing. Basically I continually ask questions because im trying to get the right answers, as you say it's just people giving their oppinion, but im left confused as people say different things which just contradict each other.
Well theres mistake number one, there are no right answers. Arnie used to train twice a day just about every day and continually gained, That wont work for most people, maybe it would for you, who knows? See my point?
Now you say cardio is bad after weights, but really how am I going to lose bodyfat doing weights only, sure I'd love to drop cardio completely out but im not sure, if I drop it out will I stop losing body fat and maybe even putting it back on, I don't know thats the problem. I mean say you wanted to cut, how would you go about it? just do weights and no cardio?
Weights burns shedloads of calories, a set of heavy squats can burn many more calories than going for a run or skipping etc. Also a big benefit of heavy weights is passive calorie consumption. That is, the more muscle mass you have, the more calories you burn just walking around day to day or sitting watching TV etc So as a very vague example,
man A might jog on a treadmill 3 times per week for 2 hours burning about 1-2000 calories on each of those days. so in a week he will offset say 6000 calories in exercise and then say
X number of calories extra on the other days on account of being fit and active
Bodybuilder man B works out for half that time (1 hour) 3 times per week, he trains heavy and trains for mass. in his workouts he burns between 1-1500 calories which totals say, again best case, 4500 cals per week directly from exercise. However, due to his more muscular make-up, he burns
X x 2 calories the rest of the time.
So if we give a fictitious value of
X as say 30 cals per hour on top of the normal human calorie use rate =
Man A per week burns 6000 + 30 x 168 (hours in a week) = 11,040 calories burnt over and above a normal human individual
Man B Per week burns 4500 + 60 x 168 = 14,580 Calories burnt over and above other normal humans.
Whilst the numbers are fictitious, the underlying algebra is correct at least in principle. So you see weights can actually burn more calories than pure cardio, also note that in the above example the bodybuilder trained half as much as the runner.
Obviously there are variables that screw this up a little, such as the extra calories required to build muscle to begin with etc
Fundamentally though, any form of dedicated training will give good weight loss
when coupled with the right diet always remeber that its controlling what goes in your mouth that shapes your body, the exercise is a given!
