Progress without stalling: double progression
When to add weight, when to add reps, and why not both at once.
Muscle responds to something going up
If you do the same thing with the same weight and the same reps for months, your body has no reason to change. Progress is not adding weight every session: it is the total load you move trending upwards over weeks, even slowly.
How double progression works
Pick a range, say 8-12 reps. Keep the same weight until you hit the top of the range on every set (12, 12, 12) with clean form. That day you add weight, even if it drops you back to 8, and start again. The load only goes up when you have earned it, not because the calendar says so.
How much to add
The smallest jump your equipment allows. On the main lifts 2.5 kg usually works; on dumbbells and isolation the available jump is already big, so it is often better to earn one more rep before moving up. Adding five kilos at a time is what turns an 8-12 range into a 5-6 range.
