Volume and Tonnage as strength training metrics
In a weightlifting sense, volume is a dimensionless unit (number of sets x number of reps). Tonnage has the dimension of weight.
When Starting Strength specifies adding 5lbs to three sets of five reps, it implies keep volume the same and increase tonnage a little. That I get. It doesn’t specify it the other way around.
However, when someone says older people need less volume (or more volume which is en vogue), I don’t know what to do. It’s really the same thing for tonnage as neither is specifying anything.
I think training can not consider volume or tonnage in any way to be productive. Where did this all come from? Am I wrong?
