How do you divide up, and train different aspects of your sport. The answer represents one “block.” Or “period.”
Then you change stuff up, so you can still progress. But you still need to train all the important aspects of your sport, so you have to think ahead.
I like the direction your head is going. Think of all those individual ways to progress. More weight, more reps, whatever you like. If you increase one “variable” at a time, it’s a “single progression.” You are adding to one thing.
In your example, you did 300x5. Thats one “session.” Next time, you did 300x8. You Progressed your reps. Then, you added some weight, and did three reps. Thats a third “session.” logically, next workout will be 310x5. The session after that will be 310x8. These sessions go together to form a “period.”
During this period, you used Double Progression. You added weights and reps. You started with 300x3, and finished with 310x8.
You can keep going this way as long as you want. The “period” can go as long as you like. But as you go farther, it will be harder and harder to keep adding weight and reps. At some point, the load you are using, and the rep scheme you are using no longer match up. They don’t work together any more. So you change something.
There are literally books full of graphs showing how long your Periods should be. Which reps go best with which loads. How much you should increase workout to workout. How long you should use different progression models. Its crazy.
There are book full of lists of exercises that work best for each body part.
Smart guys have figured this stuff out.
Adding weight in a linear way is fine, just remember, at some point, you’re going to get to a weight where you can’t do 5 reps anymore. At that point, you change something or you hurt yourself. If you have a plan, you’ll never waste time trying to figure out what to do next. It will already be clear.
