Hey dillon, as I understand it the session is set up as follows
Warm up
1 – Full body exercise (e.g power snatch)
2 – Squat
3 – Posterior chain (exercises 1-3 use the 3 week strength progression)
4a – Upper body push
4b – Upper body pull
5a – upper body push
5b – upper body pull
The UB push/pull supersets use the different rep ranges on monday and friday as outlined in the pdf
