This is a common question everybody who does cardio or aerobics wants to know. If I do x minutes of aerobic exercise, what does that mean, how many calories will I burn?

Well I'm here to tell you that it depends on factors including:

• Your body composition right now (the amount of lean body mass and body fat you have)
• How much effort or intensity you put in
• Which muscles you use
• Which exercise you choose
• Your current fitness level
• Other environmental factors such as the weather

So it's pretty hard being accurate about how many calories you burn. So don't really get too caught up by this. The fact is that it doesn't really matter. What matters is that you do the exercise. Consistency is what makes you lose fat, not having one huge workout. If you do work out consistently, you will lose weight, no questions about it.

This is the same concept for weight training as well. If you are doing weights for weight loss, again consistency is the key. You might be wondering why should you life weights for weight training?
