1 muscle round is enough

[Chuggington808]

I’m glad to hear that. I find myself in that situation as well. I’m not claiming to be the world class athlete but as far as Fortitude Training I have made my best progress at Tier 1

Everyone is different, in terms of recovery anyhow much they can put into a set. 

The CNS taxation of a MR with smith squats is different than that for a MR with cable wrist curls, too, so exercise selection matters as well.

As I've said numerous times, one of the most advanced guys to do my program was of the opinion that Tier I was plenty.  (He had a pro-level athletic background and had done true HIT training, DC training, 100 rep sets, etc.)

I personally would rather see someone doing Tier I with crazy intensity vs. Tier III and lolly-gagging through.  OTOH, to bring up weak body parts, someone who has been doing the basics (and those will / do get hit with Loading sets) might need to use a higher Tier and isolation movements to make progress in a weaker muscle group(s).

The classic example of Dorian Yates finding that the stronger he got, the less he needed to do and COULD do (and recover) in terms of training volume says a lot.
