HIIT home workouts: BurnWise

Four minutes is enough — if you do it right. You've tried the 60-minute gym sessions. You've tried the apps with 200 features. You've tried calorie counting until food became a math problem.

And the scale still doesn't move. Or it moves for two weeks, then stops. Or it drops five pounds and bounces back six the week after. The problem isn't your willpower. It's the system you've been handed.

BurnWise is built on a different premise: your body responds to short, intelligent training and honest data. Not hours. Not shame. Not another tracker collecting your weight to no end.

WHAT THE SCIENCE SAYS
A 2025 meta-analysis in the Journal of the International Society of Sports Nutrition found that high-intensity interval training:
→ Cut body fat by an average of 1.53%
→ Reduced fat mass by 1.86 kg
→ Worked best at 3+ sessions per week, 8+ weeks
→ With work intervals under 60 seconds and rest under 90
That is exactly the protocol BurnWise runs.

The fat lost first is the one that matters most: visceral belly fat, the deep abdominal fat linked to inflammation, insulin resistance, and cardiovascular disease.
As Dutch newspaper de Volkskrant summarized in its overview of the research: intensive exercise targets belly fat — and what you do matters more than how long you do it.

WHY BURNWISE WORKS WHEN OTHER APPS DIDN'T:
→ A REAL COACH, NOT A LIST OF EXERCISES
Six expert personalities. Personal trainer, special forces sergeant, physiotherapist, sports scientist, habit coach, evidence-based educator. Different voices, different cues. The coach who works for your sister won't work for you.
→ A PLAN THAT FITS YOUR REAL LIFE
Four minutes if that's what you have. Ten if you have more. Three days a week or six. Joint-safe alternatives if your knees disagree with burpees. The plan adapts to you.
→ THE SCIENCE IN PLAIN LANGUAGE
We tell you what's actually happening in your body during and after each session. No jargon. No overpromise. You stop guessing.
→ HONEST FEEDBACK WHEN YOU STALL
Most apps celebrate streaks and ignore plateaus. BurnWise has a Plateau Doctor that reads your last 14 days of data, tells you exactly why progress stopped, and suggests what to change.
→ A SYSTEM THAT PROTECTS YOU FROM YOURSELF
Calorie floors at 1200 (women) and 1500 (men), never lower. No streak-shaming. No notifications between 9 PM and 7 AM. Disordered
