Best Way To Make Consistent Gains
VOLUME training works.
HIT works.
VARIATION is key in any routine.
So, I think that a great routine would be to alternate HIT and VOLUME - giving your routine VARIATION.
Maybe something like 2 weeks of HIT and then 2 weeks of VOLUME followed by a week of active recovery.
If you prefer VOLUME: 3 weeks VOLUME and 1-2 weeks HIT.
If you prefer HIT: 3 weeks of HIT and 1-2 weeks of VOLUME.
There are many ways this could be done. I just think that both training systems are effective and at the same time, very different. And the fact that they are very different, would give your training VARIATION, which is very important.
