In previous posts I have stressed the importance of the IGF-1s (Insulin-like growth factors, type 1) in promoting body growth. To reiterate the main message of my last (post): the IGF-1s are likely to be our most important growth promoters, particularly with reference to all types of muscle, bone and connective tissues. Importantly, [...]
I have studied muscle development for most of my life - 30 of my 52 years - and after all this time there are just a few things I can say with certainty: First, exercise stimulates muscle growth; Second, proper nutrition will make your efforts in the gym pay the greatest dividends and; Third, our [...]
Depending on the intensity of the exercise and physical condition of the athlete anywhere between three and seven days are required for muscles to fully recover. This isn’t to say, however, that one should work out only once per week – this would be nearly as ineffective as overtraining.

Several key growth factors and hormones control muscle development. Of these, testosterone and insulin-like growth factor 1 (IGF-1) are extremely important.
Testosterone & IGF-1 Stimulate Muscle Growth
Testosterone is a steroid hormone that triggers the reading of genes coding for proteins essential for muscle development. By mechanistic contrast, IGF-1 promotes the physical elaboration of these proteins once [...]
