Just to note:
Any programs described here are the ones I have done in the past and present. Used also by the men I have trained with doing the same programs. Not meant for anyone as how to train, that's a personal choice each of us make. If finding a strict style, with full ROM, works for your...than great. Finding a looser, cheat or partial rep style works for you, than great.
BB'ing may be considered a experimental effort. Discovering what works for you body may require adjustments in workouts and training ideas. One method never fits everyone same goals. 20 reps will do for you what 5 reps will not and 5 reps will do for you what 20 reps will not. . Just have to find what works for you, which is usually some where in the middle. My view only, but BB'ers are the most inventive breed in all of weight training
These are only reference training styles not generally seen in BB'in magazines, video's or training books. Anything from GVT, partials, Rest/Pause, 20 rep breathing squats/cleans/DL's, bumper SLDL's, lockout training, interval training,etc.. Also different rep and set schemes (funny how so many great styles and programs are lost or forgotten over the years when it comes to weight training). This is all stuff I picked up when working out with better, bigger and stronger men than I. I am no better, or worse, than anyone else on GB..maybe just have a bit more gym time and contact with more experience weight men starting in my teenage years.
I am also somewhat into lifting history, from old time European beer hall strongman lifters to the present. Those European strongmen were unbelievable in their raw power...no drugs, no diet, no healthful living...just beer and lots of food. All wiht solid weight, or shot loaded, bars & kettle DB's.
Good Luck
Side Bar: the press from the starting position of the bar on the shoulders is the weaker position. The stronger position, of the overhead press, is the bar being lockout overhear, with a 2 to 3 inch range of motion. Same with the BP, where the strongest position is at the top lockout of 2 to 3 inches. If your best bench is 300 for 5-6 reps, you should be able to handle near the 400lbs range for a 2 to 3 inch lockout. Handling extra heavy weight can make you extra strong.
