In order to not have any redundant movements in a session, I was thinking about the difference between -
4 different exercises each going to one top set to failure
2 exercises each going to two sets to failure (one being in 6-10 range the other 10-15)
My thinking is that why not hammer fewer movements more to get better at them. Chest for example - if you’re doing a incline dumbbell press and then a machine fly - what movement of the chest muscle are you missing ? Why would you need any more exercises, instead of wasting volume on 2 more movements why not add the volume to the bread and butter lifts.
The only reason I could think to have more movements would be if one doesn’t have a strong mind muscle connection in the said muscle and so an addition of an isolation lift might be helpful.
Thanks as always
