Are you saying that increasing weight = increasing volume?
Ive always considered volume to be sets x reps and weight to be weight. I.e. you progress by either:
Increasing weight (sets and reps dont change)
or
Increasing volume (weight stays the same, reps x sets increase)
Im also not sure how you guys define intensity? Lower reps at higher weight? Taxing the CNS? Less break time between sets? Strength focussed training over sarcoplasmic hypertrophy focussed training?
