Since I have a shoulder injury that is slowly healing, I dropped the ME bench out of my routine. So everytime I do bench, I stick with the DE bench routine.
For squat days, I start off with warming up with a couple of sets of squats. I perform 2 sets of 5 with 135. Then I move up to do a set of 5 with 185, and then with 225. Some days, I can do a set of 5 with 225, on some, I can only do 3. The 225 limit is where I determine if I should continue with doing singles or triples. If I do only 3, I just stick with singles, but if I can do 5, I go on with triples. This goes on until I reach 315. From here, I'm performing either singles or doubles, plus the increment in weight goes down. I determine whether I am able to lift a heavier weight base on my form for the last set. If it looks like I'm losing form, then I just stick with the weight I'm using and perform for 3 more sets (and at this point, I'm taking at least a 3 minute break in between sets).
If I feel my squat needs some work, I will do another squat execise (with much lighter weight) to suppliment my squat routine. I will usually do front squat or zerchers.
Afterwards, I go directly to working my hamstrings. I like doing SLDL since I can pull more than I can GM, but I do GMs just for variety. If I don't do these two exercise, then I find a lat pulldown seat and jerry-rig it so I can do some modified GHR on it. If worst comes to worst and I'm pressed for time, I use the hamstring curl machine.
Then comes the ab work. I like standing crunches a lot, but the odd weighted sit-ups works as well. After, I work on my obliques. I do either landmines, Russian twists, lifts, or inverted side bends. Then for the lower back, I do reverse hypers (unfortunately, I don't have a reverse hyper bench at my gym) or pull-throughs.
If I need more work, I work on my grip strenght, or duck walk up the stairs with weights. I may also throw in pistons or some box jumps. Then I do some light cardio for recovery. I may do some stability training on these days, but then I just head on out.
If I feel I have the energy to do deadlifts, then I'll do them instead of squat. I do more squatting than I deadlift simply because my squat is weaker than my deadlift and because deadlifts are quite taxing on the body. I generally don't do triples with deadlifts though -- I stick with singles and work up to a 1RM.
If I feel too tired to go for max effort, then I switch it off with DE squats. For this, I stick mostly with the protocol for Westside. I usually leave the plyo and the other extra work out when I do DE squat. However, my time right now doesn't afford me the time to go to the gym 4x a week. In most case, I drop the DE squat and concentrate more on nailing the form down.
As for the bench, I'm sticking mostly to the DE Bench routine. I perform the DE bench as perscribed, but I also add in some chin-ups just to work my back at a different angle. For my shoulders, I stick to doing rotator cuff exercises to facilitate the recovery. I also add in some forearm exercises to suppliment my grip training. On this day, I do cardio if I got time for it. The cardio on this day is not "light" like my squat days. After that, I head out.
Anyways, to answer your question if GM has helped my squat or deadlifts, I would say they have in a way. My back isn't as week and I can maintain proper form with "heavier" weights. But GM alone was not the only thing that helped. There were other exercises that contributed to this as well; however, I would say that much of my increase was probably from me spending a lot of time on the big 3 themselves. Proper form and lots of practice will be key in the long run. Then again, I squat, bench, and deadlift not to compete, but to use these exercises to build a good foundation for other athletic endeavours. If I spend the time trying to build up my squat just for the sake of squatting, then I would be missing out on the benefits of simply squatting. The time I would have to use just to increase my PRs could be better spend on the sport that I like and want to do (i.e. MMA). Hope that helps.
