Gaining Weight from Training

Yeah, most of us have been there, done that, bought the larger size pants.

Some things to consider:

• Calories in > Calories burned = Weight gain.  It really is that simple.  Start by tracking your calories for a week or a month to get an idea of how much is going out and how much is coming in.  You may be sneaking in too many "rewards" for a good workout.  Be honest and see what it saya.
• Muscle does weigh more than fat.  That is to say, it's denser.  So, while you may look the same, if one area has been emptied of fat and filled with muscle, it will be denser and therefore heavier.
• Triathlon muscles are different from running muscles.  Most distance runners don't have very developed upper bodies because they don't have to swim as part of their races.  Likewise, there are many that say that the best thing that happened to Lance Armstrong's body was to lose a lot of the bulk he had from triathlons.  If you've added swimming to your workout regimen, you have a new batch of muscles that will add some to your weight.

I hardly ever use the scale to determine where I am at health-wise.  (I have to somewhat because the Army does. )  That being said, I look at how my clothes are fitting and how I look when I am I naked.  (Don't even waste your time with the "This thread is useless without pictures" crap.)  If I'm up three pounds but my waist is a half-inch smaller, then I am happy.

Thanks!  I have been trying to track my calories because I think I might be taking in more than I realize. 

But...how do I know how many calories I should be taking in on an average?  And...how do I know how many calories I burn from swimming, biking and running??
