Any person of any age is capable of increasing their muscle mass with a good weight training regime and mass building diet. That’s not in question. However, it’s a sad fact of life that as we get older, we all find putting on muscle mass more difficult no matter how down pat we have our diet and training.
That’s why if you have ever envisaged having a great, well-muscled body at some point in your life, it is best you don’t put it off a moment longer and get started building it right away… because the clock is always ticking.
Teenagers, of all people have a phenomenal advantage when it comes to packing on muscle mass.
During the teenage years you experience the most extreme rate of growth and most extreme physical transition in your entire life. Males not only begin producing a high amount of testosterone to give them adult male characteristics which is a critical component in building muscle mass, but, their bones are also growing due to a huge influx in HGH (human growth hormone.)
You are in effect, at this point, a walking steroid factory and growth hormone factory.
And, you can use this abundance of hormones to your advantage, if you start training and eating right. After your teenage years, things become much more difficult.
My advice is to take full advantage of this unique one-off time in your life and don’t waste it.
