I’ve been getting questions about strength and specifically how much weight should be lifted for a particular body size. This is a difficult question to answer because there are multiple factors that go into measuring and building strength.
Muscle size is only one of the factors correlated to strength. Here is a list of other factors that play a role in strength:
1. Years of training experience
2. Intensity of training
3. The specific design of the training program followed
4. Pain tolerance
6. Muscle pennation
7. Tendon Insertion
8. Limb Length
9. Length of tendon vs muscle belly
10. Neuromuscular efficiency
11. Injuries (acute and chronic)
12. Joint laxity
13. The specific exercise being tested
14. Exercise technique
15. Exercise technique coaching
16. Drug use
…and I’m sure I’m missing a few others
As you can see there are many factors other than muscle size that determine how strong you are in any one particular exercise. Judging your strength vs mine in a particular exercise doesn’t really tell you much about the size or condition of that muscle if we don’t account for all the factors above as well.
You can use strength as a general guideline as bigger muscle are indeed stronger. But keep in mind this is only a general rule and cannot be drilled down to a more specific relationship.
