Ignorant gym instructor...
I utilise the Tabata principle on either the stationery reclined bike - or sometimes the eliptical x-trainer - but usually the bike. I have been doing this for nearly a year and have lost about 4kg (9lbs?) of fat, and my body looks the best it has been for many years (I am 43!). I do this maybe 4 or 5 times a week. The problem is, a few months ago I moved to another country, joined the best gym I could find, and like it there - all good facilities. But one of the gym instructors takes a keen interest in my heart rate, that's displayed on the monitor. I try and get it as high as possible during the sprint intervals - obviously - 180 bpm is a decent target to aim for. But this knucklehead, having swallowed all that 80's claptrap about the fat burning zone or whatever actually tries to stop me pushing it, saying things like 'Never, Never, NEVER go above 150 bpm - it's dangerous'. He obviously means well but also displays his ignorance as regards contemporary fat loss methods. What should I do? Say 'look, I know more about this than you, so just f*** off and leave me alone!', or try and educate him?!? I just want to enjoy my workouts!
