How does muscle size relate to strength?

4 min read

Asked by: Angela Powell

Larger muscle fibers generally produce more force than smaller muscle fibers, which shouldn’t be much of a surprise. Bigger muscle fibers tend to be stronger muscle fibers. From Gilliver, 2009. However, while absolute strength of muscle fibers tends to increase with fiber size, relative strength tends to decrease.

How does muscle size affect strength?

Muscle strength is directly dependant upon the size of the cross-sectional area of muscle, so if after a period of training, you increase your muscle size by 50%, you will also increase the force the muscle can develop by 50%.

Does big muscles mean your strong?

While having bigger muscles does lead to the potential for having greater strength, generally speaking, optimizing muscle size and optimizing muscle strength are two different things. And you can work with your clients to achieve one or the other. It just takes different strategies, each backed by exercise research.

Does size equate to strength?

“Simply put, stronger does not necessarily equal bigger, and bigger does not necessarily equal stronger.” While strength gains may be associated with increased cross sectional area, it is not a linear relationship.

Can you have big muscles but be weak?

THE BOTTOM LINE: Yes, it is possible to be strong—and to get stronger—without having enormous muscles. But it’s likely impossible to be huge and weak because big muscles will always have a lot of strength potential.

Can muscles get stronger without getting bigger?

Your body adapts to training and gets stronger/bigger/faster/smaller because of the neural, muscular, hormonal, and skeletal changes that are the result of chosen training stimulus. Is it possible, then, to get stronger without getting bigger? Yes, it is.

Why are bodybuilders so weak?

Would be that bodybuilders are weak weak in their own way of assessing strength right they're not living up to their potential strength potential and that makes sense for a bodybuilder.

Do larger muscles equal more strength?

Generally, the bigger the muscle, the more force it can produce. However, some studies have noted that larger muscles do not have an equivalently large improvement in the specific force. This means that as the muscle gets bigger there is not an equal increase in the quality of the muscle.

Why am I getting bigger but not stronger?

The first reason why you’re not getting stronger is stimulus. There’s a big difference between training and actually training. You might have the correct form, but simply going through the motions isn’t the same as training with intent. You have to properly stress the system to manifest strength gains.

Why are some small guys so strong?

High strength on a skinny-ass person is caused by the fact that they have more fast-twitch muscle fibers, proportionally, than the other guy. This cannot be increased, although how efficiently you recruit these motor units can be increased, and the amount of motor units that you have can be increased.

Why am I strong but my muscles are small?

You Don’t Have Enough Training Volume



Hypertrophy adaptations (I.E. building muscle) are ruled by the principle of volume. The more volume in your training (more sets and reps) the greater the hypertrophy response you will get (up to a point of course).

Is it better to be stronger or bigger?

While strength is primarily a function of the central nervous system, the literature unanimously agrees that a bigger muscle is a stronger one.

Why do bigger muscles make you stronger?

Muscles increase their number of contractile elements as they get bigger. As a result, there are more components that can be producing force at a given time in a given contraction. More force production leads to greater displays of strength. Therefore, as muscles get bigger, they also get stronger.

Does bigger biceps mean more strength?

Generally, the bigger the muscle, the more force it can produce. However, some studies have noted that larger muscles do not have an equivalently large improvement in the specific force. This means that as the muscle gets bigger there is not an equal increase in the quality of the muscle.

What are 4 factors that would affect muscle strength?

Type of Muscle Fiber

  • Age. Another factor over which we have little control is age. …
  • Gender. Gender does not affect the quality of our muscle, but does influence the quantity. …
  • Limb and Muscle Length. …
  • 7 Step Guide to Becoming a Personal Trainer.
  • Point of Tendon Insertion. …
  • Other Important Factors.


Does strength come from muscles?

Physical strength might stem as much from exercising the nervous system as the muscles it controls. The findings could explain why those who lift heavier weights enjoy greater strength gains than low-load lifters despite similar growth in muscle mass.

What determines someone’s strength?

The most obvious anatomical factor that influences strength is the amount of skeletal muscle on the body. Muscles produce force, so the more muscle you have, the more force you can produce and the stronger you are.
