One thing I am thinking though, is that a routine will only really work for 3 weeks before you need to change it, so adding in some post-fatigue (extra) work will cause a lot more hypertrophy. Leg press works well for quads and you can vary the foot position every 3 weeks to get a different stimulus, change the tempo etc. You will be getting plenty of work from ]
I'm with hamburgler on this one. This is fucking terrible advise. All it will lead to is minimal progress and just swapping programs every couple weeks.
For a beginner its not that hard. Pick a rep range and stick with it. Don't make it so difficult and go all ADD swapping programs every 5 seconds. Simple tends to work better especially for squats.
