We can't find evidence that holds up here. Proponents are reasoning from mechanism or analogy rather than direct human data, and the most credible skeptics raise objections we can't dismiss.

“If quality of form is important, so maybe this is using weights, maybe you're doing squats, so you're going to do 20 seconds on and 100 seconds of rest, what you'll find is that the longer rest, even though it's 20 seconds of intense effort, followed by a longer rest of about 100 seconds, will allow you to perform more quality repetitions safely over time.”
