Lowering the weight under control is important, but not for the reason this AI slop is pretending it is. The idea that the eccentric builds more muscle than the concentric has been floating around for decades, but without even getting into motor unit recruitment or any other mechanistic details, just think about it in simple terms. Your muscles are roughly twice as strong on the eccentric, so you'll never be challenging them anywhere close to failure on that phase of the lift, and slowing it down by a few seconds doesn't change that. This 2025 meta analysis looked at 9 different studies comparing slower eccentrics in the 3-6 second range to faster ones done in just 1-2 seconds, and there was no difference in growth. Slower tempos feel harder because of greater metabolite buildup which produces more "burn", but feeling harder doesn't always equal more muscle. And let's not even get started on the whole "microtears" thing because that's a whole other can of worms. What this clip does get
