After doing a cycle of 5/3/1 (3 weeks) and doing a bunch of reading I have decided to jump on the sheiko train.
This is my first week and it's very punishing!! I have a good friend that came to workout with me and recommended it and who in one cycle put on 15lbs to each of his lifts. Frequency of workouts is less, 3 days, but frequency of the big lifts is much greater. I am doing squats or a variation 3 days a week as well as bench or a variation all the 3 days as well.

Here is a very detailed review if anyone is interested.
