Wow that is fantastic Draco!
Great progress and you deserve all the credit. Truly, an exemplary log and one in which many BP customers should turn their attention to.
This was Draco's second run with BP and he took careful notes re: his first. Further, he customized his plan according to new goals and took a bit of a leap on a new loading pattern, which was a huge success...at least insofar as the SQ:
355 X 15 reps!
Your maintenance phase is up next and I know you're putting some thought into it. I'll offer my $.02 using the SQ as an example:
Assuming a 1RM of 455lbs (I'm playing this WAY conservative) you'd be working with 365lbs. Doing so though, ensures sufficient license to work in progressive overload on the first set (suggestion) to "feel out" where you'd like to be.
Again, outstanding work and proof positive of BP's flexibility. Add the mental and physical determination displayed by someone like Draco and you wind up with well...... a 355lb x 15 squat!
