These would be the primary factors.
- High intensity/%1RM (ie 1-5 reps)
- Low Volume (2-5 sets; 2-3 exercises/day)
- Long Rest Periods (3-5 minutes rest between each set)
Now the frequency (amount of workouts/week) depends on the periodization/loading scheme you are using. If you want to consistently work near your max for each lift (ie if you are doing 3 reps, you use a weight that you could only do 3 reps with), then you will have to 1-2 workouts each done 1-2x/weekly. If you want to cycle poundages, you can do less sets/day but 5+ workouts/week.
The cool thing about just working for strength and not size is that you don’t need to lift to your max every time out. A lot of the gains made are neurological in nature. This means that the neuro-pathways (the way the signal for that exercise travels your nervous system) become more engrained and effecient. This will allow you to not only use a larger percentage of your potential muscular force, but the movement will be more refined.
Just think of when you first started MA. Some of the moves were ackward, but as you practiced them, you were able to perform them more easily and more gracefully. The same thing goes for lifting weights. The more you do it, the better you’ll be able to perform the lift.
That said, you can cycle your pundages. You can lift at or close to your max for a week, and then cycle down and use a lighter weight the next week but use the same amounts of reps. This cycling of the weight is called periodizating. A popular periodization is a step-cycle made famous by Pavel Tsatsouline. It looks as follows:
- Workout Mon-Fri
- Do Deadlift, Bench Press, and Weighted-pullups every day for 2 sets of 5 each.
- Find your 5RM (5 rep max) and subtract 45 lbs from the pull-ups and bench, and 90 lbs from the deadlift. Your first workout will be at these poundages. The next day you add 5 lbs to your bench and pull-ups & 10 lbs to your deadlift. Do this for two weeks and the final workout you should be lifting for a new 5RM in each lift. Then repeat this cycle using the new 5RM to subtract from. Theoretically, you will be hitting a new max every two weeks while gaining no weight or a minimal amount.
There is another thing called post-tentactic facillitation, which primes the nervous system to lift more. You start a 4-5RM, rest, then do your 1RM, rest, and you should be able to do a new 4-5RM, rest, and then you should be able to do a new 1RM. This is a lot more intense in nature, so you need to pick a few different exercises and split them into 3 workouts. Do a workout every other day. (ie Workout 1, Rest day, Workout 2, Rest day, Wrokout 3, Rest day, Repeat) Since this is more intense, you can only remain on such a program for a month or so before needing to mix it up again.
The options really are limitless. This is not even taking into account that unless you are a genetic mutant, then you will need a very specific diet in order to gain large amounts of mass. The lifting I’m talking about is just more geared to gaining strength without size, but really, unless you eat for it, anything you do won’t put much mass on you.
Just do some reading at places like:
http://www.crossfit.com
http://www.dragondoor.com
for workout ideas. If you don’t really have any desire to read much about this stuff at all, then you’d be best served doing the crossfit.com “workouts of the day” If your gym has minimal equipment or you have minimal daily time, then buy Pavel’s “Power to the People” at Dragondoor.com and do that workout.
They are some of the better cookie-cutter type of things out there.
