alt Hacker News> I feel like I would definitely notice if I went from 12 to 25 reps on any exercise I do.
To be clear, the implication is that 12 and 25 have different weights so they tire you the same amount. Do you think it would be a very strongly felt difference in that situation? What would the difference feel like?
Yes, this is why classic body builders like high reps because they get the pump but you can get the same growth (and there’s lots of research saying more) with training to failure with low reps and high weight but it doesn’t give you the pump.
