Back pumps during t-bar rows and bent over rows???

[Zach Strom]

Been getting them real bad in my middle and lower back during t-bar rows especially, but occasionally on bent-over rows. They go away after a couple of minutes but I think it's detrimental to my gains. Is this true? Anyone else get them? I even lighten up the weight and I still get them occasionally. They just are really inconvenient and annoying more than the pain itself

if they inhibit you pushing out reps that you could have gotten then yes it is hinfering your growth. i personally dont get them
