I researched it also some time ago, and the reason it was recommended to me as a finisher is there isn't any other bicep excercise really that can stretch and tear the fibres out as much as this excercise so any excercise done after this if used at the start of your workout will not have any effect on the fibres already broke down which are known as the deep muscle fibres which are the key to new growth, thats what finishers are for in my opinion is to get deep deep down into them.
So if you use them at the start the likes of a bb curl will not reach as far into the fibres and that stimulation is lost, as you know fibres are often related to an elastic band as they get bigger they stretch and get stronger so if you are uping the weight the fibres are stretching all the time anyway so thats when you get to the end of your workout you want to find that excercise that can give you the biggest stretch and the best breakdown of those last fibres to promote the best new growth.
Alot of people when using finishers just go for pump, but you want to be increasing your weight each week also on a finishing excercise to keep building new fibres, hope iv explained the reasoning behind using it as a finisher to you cudd2287 P.S and yes it depends on what way you look at it because you are usually seated for a db curl i would call it decline because you are moving into a decline position from seated but i do understand how i am may have confused stickup kid.
@ stickupkid
Yeah basically its just a 40-45 incline feet wrapped around the pads and concentrate on keeping your back and head into the bench for total isolation, and yes a compilation would be good even on all muscle groups to give everyone good options.
@ krs
Yeah absolutely two straight sets would be good like i say mix it up and deffo aim for the 15 rep range with the two sets, dropsets you'll be starting with less weight anyways and im sure you know it all depends on how you feel towards the end of your workout probably 20%, but definitely guys try it out and write back as to what you think of it as it really is a tough one
