Weight can increase from a variety of factors that are unrelated to muscle gain. Eating more carbs is going to result in carrying more glycogen and holding more water, which will result in weighing more. A higher sodium diet will also result in water retention.
Strength results from making muscles bigger. Greater numbers on a lift can be a result of increasing strength by making muscles bigger or getting more proficient at a movement, or more efficient at recruiting more muscles of the movement, or shortening the ROM, or altering your leverages, or being in an emotionally aroused state, etc etc. If your diet is not supporting any of those activities, it’s why you aren’t observing increasing in strength correlating with weight gain.
I whole heartedly disagree. Size, weight does not equal strength. Period. And to think one can increase his strength via increasing mass is incredibly misinformed.
Take a Judo practitioner for example, or any athlete that has to be within a certain weight range. It isn’t always the biggest, largest athlete that wins.
That is just a single example but lets look at the logistics. If one affiliates weight gain with strength, why wouldn’y an obese person be the strongest man in the world?
Of course we can’t speak on behalf of the entire population, but then one would also have to at least ponder why the biggest man in the world isn’t the strongest man as well. And that is simply because size does not equal strength. Period.
Of course an ox is stronger than an ant, but an ant, for its weight, its stronger pound for pound in its arena. And when you speak in terms of combat sports, an athlete’s strength is not indicative to their size… Including many other sports…
So then why do we attribute size to strength in lifting weights?
It’s a premonition that has been bolstered by pseudo trainers who regurgitate scientific information in their own words. In other words, people translate facts, into guesses.
I could link to any number of articles explaining how hypertrophy has a direct influence on strength, but instead I’ll just ask you this question: on average, which class of powerlifters produces the highest totals? Is it the 52 kg guys or the super heavyweights?
