This is a one time pay website to integrate an RPG style fitness plan into your life. It has good informational articles even if you don’t pay.

The articles are pretty lengthy so I just posted the one that I though would help the most and more people would be interested in.
Muscle hypertrophy involves an increase in size of skeletal muscle through a growth in size of its component cells. Two factors contribute to hypertrophy: sarcoplasmic hypertrophy, which focuses more on increased muscle glycogen storage; and myofibrillar hypertrophy, which focuses more on increased myofibril size.
Basically this explains what I posted before about the exercises that add size vs exercises that add density.
