bro the less you eat the more energy you'll have. it's an odd dynamic but its true as your seeing.
as for the routine fuck it's ridiculous man. I'm spending far too much time outside this summer to get around to wrapping it up but it's a real game changer. no lie.
It surprised the shit out of me, especially when I started with barbell curls
I warmed up to my max (no rests) and then I was expecting the following to happen because of only having 10 secs (max) pause
Set 1: 12 reps
Set 2: 9 reps
Set 3: 4 reps
Set 4: 3 reps
Set 5: 1-2 reps
What actually went down was, 12 reps, 11 reps, 11 reps, 8 reps, 6 reps
Why the fuck have I been sitting there for 1-2 mins between sets playing on my phone for years
