Well that's more volume then I ever managed on the same program.
There is so much going for this program:
Practising technique as mentioned before
Muscle mass from massive volume and frequency
Increased work capacity
Some cardio depending on rest periods
Bumps up metabolism due to amount of muscle tissue worked
So even if you came off it and your 1RM hadn't improved - which is unlikely - there is still a heap of benefits to reap from it.
Well done and upwards, onwards.
