I had a trustworthy friend of mine tell me that there is a big difference in the strength in between teenagers and adults. He said that I would notice a huge difference in the strentgh at which my muscles contract once neared the age of 18. He said I was just hitting the tip of the iceberg at this age. I'm 16 by the way and he is 20. I just want some reassurance.
