Strength by Feel cycle
 

I am starting the Strength by Feel cycle and am planning my workout for tomorrow. On the 2nd day of the cycle, it prescribes power cleans at 70%. However, it doesn't tell me 70% of what? The other days tell me to establish a xRM then use a percentage of that for my lifts. How do I pick a weight to use for this part of the lifts?

Thank you for your time!
:D

of 1rm power clean - % is always of the 1rm of the exercise unless otherwise specified.
