What is the opinion of Reddit about the
Serious Strength Training?

If you’re looking for information beyond just what exercises to do, I would highly recommend picking up a copy (or getting one at one of libraries) of Serious Strength Training . It’s an evidence-based periodization program that is highly effective.

I’ve been doing it for the few months and my strength has increased significantly.

Alternatively, if you’re more interested in hardcore strongman-style training programs, I would recommend Dinosaur Training , which is all about how to get bigger and stronger w/o supplements and lifting super heavy loads.
