Here is another useful glute activation trick. If this doesn't prove to you that everything is interconnected, then shame on you. Loosening up your calf muscle immediately provides more strength in the glutes and hip extensors. I tried it on myself, and the results were quite dramatic. Try calf rolling before a run, or before sets of squats, deadlifts, swings, or snatches. My bet is, you'll notice the exercise seems much easier immediately!
