I started off at 100KG x 20 and moved up to 125KG x 20
And that was it. I never could do it again. Never dared to. It....is by far the most difficult thing you can do in the gym

I'll break it down

1-5=EASY
6-10=Manageable
11-13=Doubt comes
14-15=Feels like stopping
16-18=There's no way I can finish this
19-20=ARGHHHHHHHHHHH!!!!!!!!

In short.....brutal beyond words.

No way...it's not a strength orientated program at all!
It's closer to size+endurance than strength if you ask me. Well basically after 6 weeks of that, the results were like this;

My waist is 30", my weight remained at 77KG yet I leaned out. Good thing! But my jeans, the legs...were tighter. Fat burns, but leg grows.

After 3 weeks of 20 rep squats, it becomes easier. A lot easier, so much so that you just feel like finishing it quickly. The set drops from 2 minutes to about 1 minute 10 seconds for all 20 repetitions. But on week 5, (breaks out old journal...) I did 120KG x 20 and suddenly it became that much harder. 122.5KG was insane. 125KG was easy again. It seems that at certain weeks/weights, the body has a hard time handling it, but readapts again.

Your food intake, that definitely will go up. You'll just eat anything and everything.

I would've continued with the 20 reppers till I hit 140KG, but I started Olympic weightlifting again, so there was no time to waste doing 20 rep squats. The best part was really, the melting away of fat.
