Hi everyone!

I got a Groupon for one month of CrossFit. I started about a week ago and have attended four classes. It's tough but I have been enjoying it!

However, I weighed-in today and I am up 2 pounds and I feel really depressed and discouraged. I know I am working my body differently than my usual cardio and my muscles might be like WOAH but does this sound normal?

I've been tracking on MFP of course, as well as trying to limit carbs and increase protein.

Thoughts, suggestions, help?! frown

I wouldn't worry about it yet. I've been doing Crossfit 3x a week for about 8 months. I've only gone down about 10 pounds, but I've lost more than 2 inches at my waist - and I was not being careful about my diet until the last 3-4 months, either.

I'm sure if you start taking your measurements as often as you check your weight, you'll see your body composition changing.

I got this from another post, but I think it explains it best:


Probably the most common question I get when I release a new exercise program is, "Help! I'm gaining weight! Am I doing something wrong?" This is a common phenomenon with any new exercise program, Turbo Kick, Turbo Jam, Hip Hop Hustle, you name it! It's especially common (and temporary) with intense strength training programs like ChaLEAN Extreme or Tony Horton's P90X.

The motivation to start a new exercise program is almost always to lose weight loss. However, what most personal trainers know and most at-home exercisers do not, is that a new exercise program often can cause an immediate (and temporary) increase on the scale. (Notice I didn't say weight gain! I'll explain.) This common increase in the scale is also the reason why perhaps millions of people start and then quickly quit their resolution to get fit.

The temporary weight gain explained:
When someone starts a new exercise program, they often experience muscle soreness. The more intense and "unfamiliar" the program, the more intense the muscle soreness. This soreness is most prevalent 24 to 48 hours after each workout. In the first few weeks of a new program, soreness is the body trying to
"protect and defend" the effected or targeted tissue. Exercise physiologists refer to this as delayed-onset muscle soreness, or DOMS.

This type of soreness is thought to be caused by tissue breakdown or microscopic tears in muscle tissue. When this happens the body protects the tissue. The muscle becomes inflamed and slightly swollen with fluid retention. This temporary retention of fluid can result in a 3- to 4-pound weight gain within a few weeks of a new program. Keep in mind that muscle soreness is not necessarily a reflection of how hard you worked. In fact, some people feel no signs of muscle soreness, yet will experience the muscle protection mechanisms of water retention and slight swelling.

Most people are motivated enough to put up with this temporary muscle soreness. Yet, many, especially those who really need immediate weight loss to keep them motivated in those first couple of weeks become discouraged and quit!

When I worked with a group of 70 test participants during the development stages of ChaLEAN Extreme, this happened. Who was the most upset and discouraged? You guessed it... the women! I'm happy to report with absolutely every single woman (and man) in our group, the weight increase was temporary and never lasted more than 2 weeks before they started to see a major drop in the scale. However, these people had the advantage of working with someone who was able to explain to them why this was happening and assure them the weight would come off if they stuck to the nutrition plan and stayed true to the program.

For those of you who are following the ChaLEAN Extreme phase plan, keep in mind that when you start each phase, your body will be "in shock" again. Don't be surprised or discouraged if you experience a temporary gain on the scale the first week of each phase.

My own personal example of this is running 10K's. I don't do it very often, maybe 1 or 2x a year. Even though I run on a regular basis, when you run a race you push much harder. It's natural for me to be "insanely" sore the next day. Its also very common for me to see the scale jump 4 pounds the next day from forcing fluids post race and the resulting DOMS. Even though I know the cause of it, it's still a bummer. We're all human and hard work should mean "results". Hard work equals results, but our bodies are amazing machines and they know how to protect us from hurting our selves. Soreness forces you to give those muscles a break :) Ultimately you will lose the weight and you will change your metabolism in the process.

The key is understanding that this is a normal and temporary and stick with the program!!

When to be concerned:
If you experience a significant weight gain (exceeding 5 pounds) which does not begin to decrease rapidly after the second week, guess what it is??? I'll give you one hint... you put it in your mouth and chew it. You know it! You're food (or calorie laden beverages). Newsflash friends.. exercise doesn't make you gain weight. Consuming more food than you burn makes you gain weight!

So if after two weeks you are not losing weight, have gained weight that's not coming off, it's time to take a close and honest look at your food intake. It's time to find out what you're burning in calories each day. Have your RMR or BMR tested. This can be done for less than $50 and the information is invaluable. It takes out the guess work. Google "hydrostatic body fat testing _______ " and insert the name of the big city you're closest too. Companies that do HBFT also do BMR testing. Knowledge is king.

I'm gaining weight, but I'm sure it's muscle:
Possibly, but if you're following ChaLEAN Extreme correctly, you should be losing fat and gaining muscle and the fat loss should be much more substantial than the rate at which you can physically put on muscle. This is even true for they guys. Of the 70 plus people in my test group, every single one of them lost body fat and gained muscle and not one of them gained weight. I believe the average weight loss after 4 months was 28 pounds with many people losing 40 plus pounds. Even the men, who as you can see put on a lot of muscle, were seeing huge drops in the scale. We tested their muscle composition at the beginning and at the end and 100% of the participants maintained or gained muscle while achieving substantial weight loss. That's the key to keeping weight off long term, i.e. muscle. Muscle burns fat. But you've heard me say that before.

Moral of the story:
Be patient young grass hopper. You'll be lean and mean in no time! "

I took measurements last week but since it has only been a week I want to give it a bit longer to remeasure. :)

Thank you ulke, that was very insightful and makes a lot of sense! CrossFit is very intense and my body has been very shocked and very sore this past week. Since I know I am following my diet and it's not the food I will give it another week and a half and see how things are looking. :)

So what are the results? I just started crossfit this past week, and I a gained two lbs. Did you eventually lose weight?

Can you share your results with me? I just started crossfit and I too put on weight the first week.

I joined Crossfit almost a month ago and have gained weight. I am hoping my second month I will start seeing a drop in the scale. It is very discouraging to say the least, but I am sticking to it and hoping for the best.

If you build up muscles you will gain weight, that's normal ...
2 LBS difference is nothing,
always keep in mind that any measurement is only a snapshot of the whole day ...

What really counts if you do exercises is "body fat" ...

I wouldn't emphasize the number on the scale for assessments - only body girth measurements (tape) and body composition measurement results. I would also choose one constant day of the week and time to do assessments - preferably early in the morning. Also, keep in mind that if you use those handheld bioimpedence body fat analyzers, that they are very sensitive to a number of variables such as body temperature and hormones. So do not use them after exercising (or even exercise the night before) or during menstrual cycles. Generally they have a standard deviation of near 4%, as well. I'm a personal trainer and test the devices daily to make sure they are operational and notice it gives me a standard deviation range of approximately 2% from day to day.

And? What eventually happened? Ive been doing CF for three weeks now (I'm the fattest person there and I push myself like a demon), I have changed my ebtire world to make this work, eaten clean for four weeks now, not a drop of booze and no cigs (cold turkey).... BUT I'm up almost 2kg??????????? I wont stop going, because I absolutely love it and its more important to me to beat my last time than worry about my fat roll but with 30+ kg to lose, id like to know rhis will be an eventual outcome????

To the gals who wonder what happens. If you continue on a path of crossfit, you will most definitely gain muscle and therefore gain weight. I started crossfit at 123 pounds, and am now more like 133 pounds about a year later. I am bigger, but not fatter. If you have a lot to lose, you will definitely drop on the scale in time with the right diet and regular crossfit.

Completely normal

I did cross fit for about a year and did get fatter. The reason, looking back is obvious, I was so sore from the couple of workouts I did a week, although I was working out harder, I was working out a lot less then when I was running and therefore burning a lot less calories. I never got over the "I am sore all the time" phase and really started to hate it - which compounded the problem since I would work out even less. I am back to running at least four times a week and am much fitter and happier for it. The added bonus is my chronic shoulder injury is now healing. Cross fit is great for some people - I'm not one of them.

Slight weight gain at the beginning of any workout regimen is totally normal. Your body is holding on to excess water after such workouts and you will lose the water weight.

If you want to see results, you must be careful with your diet. Otherwise, all of your hard work won't pay off! The unfortunate truth is that no matter how hard you work, it still boils down to 80% diet, 20% exercise.

CrossFit is a great way to lose weight as long as you are dedicated to it and eat clean.
