The biggest training mistake when getting lean
Does getting lean mean turning every workout into a hunt for more calories burned? Chris Bumstead's answer is to stop treating cardio as a magic shortcut, especially if it means giving up time with the weights.
In "The biggest training mistake when getting lean", he identifies that trade-off as the mistake. Between his explanation and a brief clip of machine-based leg exercises, Bumstead makes the case for preserving muscle rather than simply adding more activity. He points to muscle's role in resting metabolism and pushes back on the idea that higher-volume lifting necessarily produces a much bigger calorie burn.
The Short drew an estimated 144,000 views in its first day, more than five times his usual opening for the format. Its comment section was also more than four times as busy as usual.
Viewers aren't only discussing getting lean. Several distinguish cardio's cardiovascular benefits from its use for weight loss; others question how reliably calorie expenditure can be compared across different workouts. That gives the conversation a useful distinction: protecting a weight-training session isn't the same question as whether cardio belongs in a routine.
Bumstead has been approaching the subject from several directions. His nearby uploads include "Too much cardio while dieting?" and "Using gym performance as feedback", placing this warning within a run of practical questions about what to keep, change and pay attention to while getting lean.

Not many discuss cardio regards its importance for heart health...always about diet/weight
@jcoll7361See it on YouTubeAs much as I believe him there are too many variables when it comes to calories burned while working out (which muscle groups being worked, relative effort, etc) - with steps you can at least get a rough estimate
