I have used the program you linked to before, and it “didn’t work” for me (im 5’11 240#). Worked wonders for my brother though (+40kg squat in 8 weeks 6’4 188#)
Westside is a funny thing. It works like a charm but you have to understand a lot about yourself and the system to make it work.
It’s a good start to look at a pre developed workout such as this or WSSB, and then adapting it to you specifically. You need to know why you are doing each exercise.
That is the upside/downside of the system. There are no cookie cutter programs that work for everybody.
Now to the questions: Yes you are strong enough. Do you have the work capacity? Westside is only easy on paper.
The equipment does not make the routine. If you can’t get a GHR do romanian deadlifts etc. The box is a minimum though.
I am no expert, but I have seen good results using a modified westside system (based off this workout).
I believe I have the work capacity. I have been doing a lot of Chad Waterbury’s programs for hypertrophy and I am ready to move onto strength. Most of my workouts last 1 hour 30 mins to 2 hours.
Westside for skinny bastards…I’m not really skinny, though. I do plan to bulk up soon, though.
