If you're detrained, gains are insane. That's what's driving most tRaNsForMatIoNs too.
A wanna be influencer builds muscle for 3 years, get big, slacks 6 months and gets detrained and a little chubby on purpose, then cuts back on food and lifts hard again.
Muscle memory -> enormous gains while recomping. Now go viral with your miracle transformation story and sell bullshit to unknowing average Joe: "Sixpack in 6 weeks".
You're looking at 3 years of work homie, can't be done in 6 weeks.
