Am I doing this wrong?!!!

I had been for a month and a half working out at the gym at the aero-machine thinking that if I worked at 80 percent of my target heart rate (considering my age is 18) is around 160 bpm.... But then I was talking to some guys who said what I was doing was a cardio-workout, not fat-burning. They said I have gone beyond the fat-burning level and now is burning muscle... They advised I lower my intensity to around 140 bpm to maintain fat burning.... Is this true?!!!! :confused:


Also on a sidenote, I found out from my friends that my chicken teriyaki meal I have everyday at my school's student center is not healthy at all - and should have instead a taco-salad without the shell. What do you guys think?
 
the guys are right, but not giving you all the details. to burn entirely in the fat-burning zone, then yes, you need to keep your HR down. However, you burn more fat and calories in the cardio zone ... the downside is that you also burn protein (muscle). There are two ways to optimize your training ... one is to do HIIT (High Intensity Interval Training) - search this forum for details (basically changing your intensity during your workout from low to high intensity) - the other is to eat a high protein meal before and after your workout so that it burns the readily available protein instead of from your muscle.

If you believe in the low-carb meal plans, then the toco salid is a good way to go ... your chicken teriyaki would also be good if you took out the teriyaki :)
 
HIIT involves more like 45 sec slower pace, 15 seconds higher pace... I use it while walking, b/c i'm not into running at all. I will walk at a decent pace for 45 seconds, and then for 15 i'll jog. It keeps my heart rate up, as well as giving me a good sustained workout.
 
hmm... taco salad isn't that good either, because you would have all the greasy ground beef, and the dressing or sour cream. I like a nice garden salad with some chunks of lean chicken breast, and light dressing
 
my HIIT consists of 1/4 miles walking pace, usually around 4.5 on the treadmill, the next interval is a 1/4 mile at 6.5 and then back to 4.5 for the next 1/4 mile and so on increasing the speed of the faster quarter by .5 each time till I reach 8 or 8.5 then I go back down, like a pyramid. I do 4 to 5 miles this way which takes about 45-50 min but you can get away with 20-25 min like this and get a good calorie burn. I have read that the amount of time I spend is actually too long but sometimes I enjoy it too much to stop :)
 
Interval training

Or try a minuite of all out as fast as you can go and then two minuits of slow and easy. do this for 15 minutes. It pretty intense, but a great workout
