A myth. Nonsense.
You can hit the THR all day long and still gain fat. Where's the proof? How do we know that elevating HR burns that much more fat?
Meanwhile, train exactly as you do now, cut 1000 calories from your diet and walk 10 miles a day. You will NEVER reach the THR they say is necessary. Yet, by the end of the month, you will hjave lost fat. Guaranteed. It's all pseudo science. Don't believe it.
