Leangains is THE go-to "fitness" (I am not sure the sites' administrator, mr. Berkhan, is fond of that term, but in the name of categorizing...) resource of the ulbator head honcho. The site is seldom updated nowadays, but all the free information already posted is more than enough to let progress for years in the gym. I have read some of the posts numerous times, but I still go back for advice every now and then. Although inclined primarily towards IF (intermittent fasting), the lifting advice is no-nonsense and top notch. Applying a leangains approach, interpreted through the lenses of the ulbator head honcho of course, is pretty much the sole reason I am currently able to deadlift 455 lbs, going for 500 before this year comes to an end.
Today the leangains site had one of its scarce updates, with a link to a new IF report. The report tends towards the scientific kind, but if you are thusly inclined, it will be well worth your time.
In short, leangains is a great resource that will help you get closer to the much coveted ulbator ideal.
Not for Pussies!
