Fat burn

[jacobfernandas]

I'm trying to increase muscle mass but am noticing the start of a jelly belly. I'm not fat... have been weight lifting at the gym for about 3 years and have only managed to put on about 3kg in that time!!! So recently I started to eat more, probably not the cleanest nutritional values though. On top of that I also take protein. Anyway, that's some background stuff.

I use the cardio machines at the gym - cross trainer, treadmill & cycle. Rather then do 30 minutes on each machine (3 machines each session) at 80% of my max heart rate. I do 10 minutes on each at 100% heart rate achieve the same result (some times it goes a little over 100%). I simply don't have the time to do it at 80% and on top of that I get bored.

My posting here is to ask: Will working at 100% rather then 80% burn muscle instead of body fat? I'm thinking that maybe this is where I'm going wrong with my goal of trying to bulk up.

My stats are at the bottom.

Cheers!

Wow, you are really working hard on exercising. I can't do that, since I am underweight by 1.2kg. I can't answer your question, but what I know is that we burn fats in our bodies and we build muscles through exercise... I'm not sure if it's clear to you, though...

If you consider the fitness range zone 70-80% of max HR, the answer is "very probably yes".

Training in this zone gives more muscles than lower zones and less fat burned. As muscles are heavier than fat, you can even gain weight . But, it gives also a higher total of calories burned. And fitness cannot be neglected.

However, you should first think about what you eat. This is the essential part of weight loss. So, first thing to do is to change your eating habits. Eat better (less fat, more vegetables and fruit), eliminate junk food and sodas, diminish sweets.

Exercising is just a complement that cannot by itself help you to lose weight (about 60-70% of weight loss are eating habits and exercising is the rest).
