Yeah looks just like that. So the seat position should be such that if the weight was > your BW, you'd be lifted off the seat in the top position.. is that it?
Or is the seat height correct when your legs are at 90 deg at the knees and torso.
Set the seat so you can just touch the handles, lift the thigh pad to the top, grab handles, sit down, lift thigh to dis lodge the pad until it locks you in, pull, slow and controlled.
if you're at a gym where there is this and a pullover, they are two machines that really hit the lats like no other.
set the pullover up its rarely used, shoulder in line with axsis, load up 40 kg, it's all you'll need.
go to the high row, with 40 kg rep to failure, should be around 120 sec, don't count reps, just go until you can't move, (DONT USE MOMENTUM), go straight to the pullover and do the same, it's important to go full range on this, right back as far as you can go, all the way to the tummy, do not use the hands, push through with the elbow, place the hands at the side of the bar, not on top.
