Thank you Jim, that's a good guideline to follow when I'm cycling through different 6 week blocks. I have found that the amount on assistance is easy to program according to how you feel after your main lifts.
Rave - You're right. What I meant that assistance is not_that_important part in training compared to other aspects:
- Speed work.
- Volume/intensity work in main lifts.
- Mobility and form work.
I first make sure these things are allright before I think about the assistance. Of course assistance is not useless, doing rep work in chins have made my back grow a lot and probably saved my shitty shoulders from aching all the time.
But if I must choose to do FSL work or assistance work in squats after my 5/3/1 sets, I'll normally go towards the FSL. But that is just me, I really haven't try assistance based templates, or any kind of "weak point"-training. I just hit the main movements as hard as I can, and keep the assistance at minimum.
Some day I may need to change it (this could be clever thing to do actually with squats, because I have some serious problems with my operated left leg, and I really haven't found any clear solution to the problem), but not planning to do so for at least 4 months.
