Paul Revelia, a physique coach, publishes articles on a daily basis about how he employs steady-state cardio to help him lose weight.
When it comes to workout time, HIIT has an obvious benefit because you'll burn more calories in a shorter period of time than you would during a lower-intensity session.
However, as Beaugrand says, this also necessitates a higher level of competence. "If you're doing sprints, you need to be able to do it at all-out effort,
he says, "whereas with lower or moderate intensity, we don't need as much expertise, and we can do things like walking, riding our bikes, or going on a hike."
"Does HIIT cardio make sense if your primary goal is bodybuilding or a combat sport? It's all about taking a look at your overall timetable and objectives."
