Bret Contreras's articles are great! I really like how he tests everything and then has the results in numbers and then lists the best exercises for each group. Two lifts I have been doing of his that will from here on out be a staple to my programs are the Weighted Hip Thrusts and the Weighted Glute Bridge. Those two lifts have helped my speed and strength tremendously. IMO his glute research is some of the most revolutionary stuff to come out in a long time. I think (especially in the sports & conditioning side) his work will really begin to become mainstream.
