Yes…I have the same “problem”. Whenever I start working out, I ALWAYS gain weight before I lose it. The way it was explained to me is that muscle weighs more than fat. So when you first start working out, you tend to build muscle BEFORE you lose the fat so now you body is carrying muscle AND fat. As you build muscle, you burn the fat faster and your weight starts to go down. 

That’s why I stay away from the scale. I focus on how I look, how my clothes fit, and how I feel. I have a pair of “inspiration pants” that I try on every few weeks to see the progress. Right now I can get them over my booty where before I couldn’t get them past my thighs…LOL. That scale can really mess you up…especially when you are first starting out.

I’ve definitely noticed this and it can be really, really frustrating in the beginning!  When I was doing P90x I gained about 5 pounds, although I didn’t get any bigger physically.  I did get stronger and more muscular, however.  I started working out again last week after taking about 3 weeks off and lost two pounds, immediately followed by a 2 pound gain.  I’m chalking it up to water retention, otherwise I’d probably throw my scale out the window whilst screaming at this point (I mean honestly, how many times can you go up and down the same damn two pounds???)

That would be my suspicion as well, water retention.  As long as you are not eating more, that seems the likely culprit to me.

Ugh, it is so frustrating when you are doing everything right & the scale numbers go the wrong way!

Also it’s important to continue to monitor your food intake. When you start burning more calories, you get more hungry and it’s easy to eat a little more.

I have this happen to me, too. When I first started working out, I was mainly weight training and I gained weight or would be at a standstill. I started pushing my cardio harder in addition to the weight training and I started to lose weight again.

Muscle weighs more than fat, so if you start building muscle, you’re going to weigh more for awhile.. but muscle burns more calories. Also.. the tearing muscle thing is true according to my FH who has a degree in Kinesiology (the study of the movement of the body). I kept gaining and losing the same 3 lbs this past month and was getting really discouraged, but then I realized this past month I was upping my weight in all the weight training I was doing and I started experiencing the muscle tears again. My body finally got use to it this past week and I kept those 3 lbs off and lost 2 more!

Good luck on your weight loss, don’t focus too much on the scale.. focus on how you feel. Even when I gained or was at a standstill, I was losing inches.

Your trainer is right about the water weight.  Your muscles retain more what when they are trying to repair themselves post-workout.  While its true that muscle weighs more than fat, if you’re early in your workout process, that probably isn’t what is happening yet.  Sadly for us women, it can take months of working out to gain just 1 pound of additional muscle (other than the water retention in your muscles).

Overall, don’t worry about it, it will come off in a few days 🙂

I have been an aerobics instructor for close to 8 years and yes, the trainer is telling you the truth.  Give it time. 

However, the muscle weighs more than fat kills me.  1 lb muscle = 1 lb fat!  A pound is a pound!  But, 1 lb muscles takes up less room than 1 lb fat in your body.

Also take a look at your sodium intake.  That makes you retain water.

Thank you! That muscle weighs more than fat thing is killing me. Muscle is denser than fat, but a pound is pound.

That’s the nice thing about having a scale that measure’s body fat. I know that the method used in home scales to measure fat is not very accurate, but it’s a good tool when you just want to see the difference over time.

Since Jan 1 I’ve only lost 3 pounds of weight, but I’ve lost almost 5 pounds of fat so I’m pretty excited about that. 🙂
