Some powerlifters (and bodybuilders) believe that they become stronger with added mass- regardless of whether it is fat or muscle. Granted, the preference would be muscle, but the reality (especially in Powerlifting) is that the bulk is fat. Proportionately the fat to muscle content is much higher than that of (even an "offseason") competitive Bodybuilder.
Here's the question: "Do you think fat ads an advantage to heavier lifting?"
Some might say that the extra fat and water protects the joints better, which in turn makes the joints more stable, stronger and less likely to be injured
Here's the kicker though: Wouldn't intramuscular fat (the fat between the muscle fibers) hinder muscular contraction? This in turn would make you weaker, not stronger.
This leads me to believe that the leaner you are, the stronger you will be.
Thoughts?
