Terry Todd, mentor of Hafthor Julius Bjornsson (World's Strongest Man), was an American powerlifter, and Olympic weightlifter. At the 1965 Nationals, Todd became the first man to squat more than 700 lbs. in competition, by squatting 710 lbs!
Mr. Todd favored partial movements in his training to gain size and strength. Terry cited that if you do heavy partial squats, your full squat will almost always increase; if you do heavy partial deadlifts, your regular deadlift will increase; if you do heavy partial bench presses, your regular bench press will increase, and so on.
Terry Todd developed the following training philosophy/thoughts with weightlifting star Paul Anderson. Have fun! - Mr. Berg
Exercise #1 Drive off chest - Either have your workout partners place the bar on your chest or place the bar on a rack or on raised benches so that it touches your chest. Use a weight that is greater than you can lift all the way up, but one that is light enough to allow you to drive the weights several inches into the air. Use low repetitions.
Exercise #2: Lockouts - You will need to use a rack or some type of support for this, so that you can place the bar at a height that is just above your "sticking point." Lift the weight from there to arm's length for several repetitions (one to six), being careful to use the heaviest weight you can lift for the number of reps that you perform.
Exercise #1: Half Squat - Using a rack or stable squat stand, place the bar at a height just above your "sticking point." Use a heavy weight and get as many reps per set as you can (up to ten - if you can do more than ten, increase the weight on the bar). This exercise can be done in the same way as traditional squat are done (walking away from the stands squatting, and returning the bar to the stands), except that it is rather risky unless you have experienced spotters to help you, because if you go a bit too low or if you try one more rep than you can make, you will be in bad trouble.
Exercise #2: Top squat - Using a rack or very stable squat stands place the bar about six inches from your final position (legs locked) in the squat. Use a heavy weight and get as many reps as you can without bouncing the bar on the racks. Add weight if you can do more than ten reps. It is not adviable to do this exercise unless you have access to a rack that allows you to place the bar inside the rack for maximum safety.
Exercise #1: Deadlift starts - Start as you would in a regular deadlift, except you will use a weight that is too heavy for you to do a full deadlift with. Pull the weight as high as you can for several reps (one to three), being careful to maintain, as nearly as possible, your regular starting position. Use straps to assist your grip if you need them.
Exercise #2: Deadlift Finishes - The great Bob Peoples called this High Side power, and you can get it by placing the bar just above your "sticking point" (usually just above the knees) and doing several reps (one to three) with the heaviest weight you can handle. You will probably need to use straps in this exercise.
Note: According to Terry Todd there are several ways to work these partial movements into your training program. You can either pick one day each week and devote it to partial movements for all the lifts or you can add a couple of sets of the appropriate exercise or exercises after you finish your regular program. For instance, you could do a couple sets of Bench Press Drives and a couple sets of Bench Press Lockouts after you did your regular bench press routine.
If you do this, however, be careful not to overwork, as the partial movements are very taxing. if you work as hard on them as you should. Give them a try.
