Lost 3kg of Muscle in a Month

Hi guys,

So i just got my girth measurements and skin folds redone today after about a month and a half of trying a bulk. I was planning to continue for at least another 2 months but the results i got back were quite alarming. Hopefully the differences in the skin folds may have been down to the different gym supervisors who did them, i.e slightly different techniques or something but here are a few results and just want some feedback.

   16/1/13      -     21/2/13

Weight: 75.8 - 80.5kg
R/Bicep: 28.3 - 31cm
Chest: 98.8 - 99.5
Waist: 80.5 - 79
L/thigh: 52.5 - 53.2
r/claf: 35 - 37.1
BF% 6.44 - 10.15

So yeah ive been doing a FBW every other day, and eating really clean :frowning: The calculator ive used is based on the 4-point skin fold, and breaks it down into LBW and Fat weight. It says that ive gone from 75.32kg LBW to 72.33kg and from 5.18kg of bf to 8.17kg!!! WTF? Is it really plausible that i can loose almost 3 kgs of muscle mass in a month training every 2nd day? Any advice or similar experiences would really help cause im kinda panicing atm!

Look at your measurements. Do you really think you can increase the size of your arms and shoulders and it means you lost muscle? Whatever happened, you definitely gained clean tissue - the two measurements I just mentioned are a clear indicator, especially in combination with your decreased waist size.

Long story short: either your caliper numbers or your calculating formula are flawed, you didn’t lose muscle.

What does it look like in the mirror. If you gained a full 3% bodyfat in that short of time it would be easily noticed.

You actually got leaner. You lost size in your waist, and gained in all of those locations so you lost fat and gained muscle. Just for fun, what are your lifts before and now?

If you’re a guy, a decrease in waist size almost unilaterally means you lost fat. This is especially true if you gained weight. Whatever formula you are using is clearly flawed.

It might different time of day, more salt/water retention, double error each time the technique might be a few % wrong so a few too big, a few too small = just irrelevant numbers.
Yes scale + waist + miror = credible indicator. Just do them at same time to minimize fluctuations.

You need to get off of your fatter ass and work out more.

That or have the same person do the testing each time, at the same time as before, hopefully with as many variables kept constant like time, meal or meals, crap or no crap, and how much water intake.

OR, don’t worry about it and just lift heavy stuff. You weigh about 175 lbs, or 80 kg. Get some heavy doses of food, iron, and rest. Worry about fat when you can flex something under it.

Thats awsum news! yessss! the past month i tended to ease of the amount of weight and concentrate more on slower reps, and slower negatives and actually noticed a lot more activation deeper in my muscles so i dont really have any weights to compare. Although i do seem to be gradually working my way up along the dumbbell rack which is always a good sign :wink:
