Depends how much warming up you need to do and the time of the day...
evenings, my back is more with it
bar x 5-6
60 x 2
100 x1
130 x1
150 x1
160 x1
then I hit 165 or 170 and then go more if I am feeling on it, then drop down for 2 doubles...
I was doing 140 > 160 jumps earlier as well but I need to regain more strength first.
Mornings I'll do a few more like so
bar x 5-6
bar x 4
60 x 3
100 1-2
130
150
160
same as above
End of the session I can go
100
140
170
When I hit 180 I went 160 to 180. Just felt f0cking on it.
Looks about right, but I'd say too many with 70, but if you need to do 5 then you need to do 5. Just do the minimun to squat so you don't break yourself when you go heavy
