Am I gaining muscle from all this cardio?

Oceanborn2

My calorie intake is around 2000 average per day (counted meticulously) and my TDEE for having a desk job is around 2100 calories so the IIFYM calculator says. I've introduced cardio into my routine and I'm currently getting about 25 miles per week in on the treadmill. Before running I was completely sedentary.

For some reason the scale says I'm 8-9 lbs heavier than when I started. There's no way that that weight is bad weight, it MUST be muscle or something. I'm not panicking at this point because I'm positive I'm doing the right thing, I'm just a little confused as to why my weight shot up.

I'm not even very interested in the scale, I'm interested in shedding this last 10 lbs and having that reflect in the mirror. So it's funny that I've gained 10 lbs, when I was trying to do the opposite!

increasing muscle mass requires a caloric surplus with heavy resistance (weight lifting) exercise.....so the answer is no, you did not gain 8 pounds of muscle from cardio plus a caloric deficit

It's not possible for you to put on 8lbs of muscle that rapidly. Further you are female, at best you could put on 8lbs of muscle in a year or 2 of intense strength training exercises.

You cannot gain muscle from cardio.

A rapid weight gain is food related, like say water. If you started a new routine and you're drinking plenty of water, your body may decide to hold onto that water for a while. That's good, its healthy weight gain. It would mean you are hydrated.

It's also possible you aren't counting your calories right.

The most muscle you can gain is an ounce a day, and won't happen on the treadmill.

Water retention. Sodium intake from the day prior. Yet to do your morning constitutional. Can all contribute.

The real reason your scale reads 8-9 pounds heavier than when you started will be found here...

You are probably eating more than you think. No, it's not muscle.

No you didn't & the only cardio exercise proven to gain muscle in a surplus is hill sprint repeats.

Cardiovascular training builds up muscle endurance and not muscle size. So, no you're not gaining muscle especially IF you're on a deficit.

No, you don't build appreciable muscle doing cardio.

It is VERY difficult to build muscle and with the exception of newbie gains, not possible in a deficit. Probably water, poop and a little of that increase is due to eating above maintenance.
