The controversies over cardio for fat loss are endless - steady state versus intervals, fed versus fasted, long and easy versus short and intense, and so on. Obviously cardio training generates quite an interest. Sadly, majority of people are still doing things terribly wrong and it’s killing their results.
A lot of people are careless about burning enough darn calories.
Probably they are too busy worrying about the “proper” type of exercise (which machine or activity), the mode (steady state or intervals), the “optimal” ratio of intervals, or the “best” duration.
Some people coast along on the treadmill at 2.3 miles per hour or some similar sloth-like pace and they think that just by hitting a TIME goal, such as 45 or 60 minutes, that with “X” duration completed, they are assured to get the results they want.
On the other extreme, we have folks who have found or created some mega-intense, super-duper short training protocol like the “4-minute wonder workout from Japan.” Just because the workout is high in intensity and it is performed in intervals, they too think they are assured to get the results they want.
What’s missing in both cases is the realization that total fat loss over time is a function of total calories burned over time (assuming you don’t blow your diet, of course).
AND…
Total calories burned is a product of INTENSITY times DURATION, not intensity OR duration.
Too much focus on one variable at the exclusion of the other can lead to a less than optimal total calorie burn and disappointing results. And remember, intensity and duration are *variables* not absolutes! (“Variable” means you can change them… even if your “guru” says you can’t!)
When you understand the relationship and interplay between INTENSITY X DURATION you will find a “SWEET SPOT” where the multiplier effect of those variables produces the maximal calorie burn and maximum fat loss, based on your current health condition and your need for time efficiency.
