I know you're meant to add volume progressively. For example, Eric Helm's Strength Pyramid says add roughly 10 reps per muscle group per session and repeat for 6 weeks.
However, add 10 reps of what?
Are you meant to be linearly progressing throughout the 6 weeks i.e. adding weight and dropping reps every week? That would probably mean you'd have to do many more sets at higher weights in order to keep going up by 10 reps per muscle group every week. And that would seem way too intense for the accumulation phase.
Or do you just keep the weight the same and literally add those 10 reps (at the same weight) in however many sets it takes to hit your rep total?
So, if you do sets of 8 reps, your 6 week accumulation phase would look like;
Week 1: (200lbs x 8 reps x 3 sets) = 24 reps total
Week 2: (200lbs x 8 reps x 4 sets) + (200lbs x 2 reps x 1 set) = 34 reps total
Week 3: (200lbs x 8 reps x 5 sets) + (200lbs x 4 reps x 1 set) = 44 reps total
Week 4: (200lbs x 8 reps x 6 sets) + (200lbs x 6 reps x 1 set) = 54 reps total
Week 5: (200lbs x 8 reps x 8 sets) = 64 reps total
Week 6: (200lbs x 8 reps x 9 sets) + (200lbs x 2 reps x 1 set) = 74 reps total
Would the above work as an accumulation phase? Is that what you're meant to do on an accumulation phase?
