Hey all, so i been lifting on and off for about 6 years or more so im not exactly new to this but i had a question about bicep curls. So i'd say for the last 2 years or so, i have been doing standing bicep curls with either dumbells or a barbell but for some reason i stopped getting the huge pump and very little if any soreness at all even after going to faliure. So for what ever reason i decided to try sitting curls and i got a huge pump in my bi's and was sore for 3 days after.
Question is, what is the science or broscience behind this?
