Okay.
I have people asked me this before in PMs.Why despite following
HIIT and weights.They still cant lose weight.
A simple reason would be that, you are losing fat and gaining
muscle at the same time.Therefore, your weight might not go down or
infact increase.But this is an increment in lean mass.Nothing to be
afraid of.
Muscles weigh more than fats.
The better method IMHO ought to be going for a body composition
test BEFORE and AFTER.
The BodyFat% should drop and lean mass increases when comparing
both data of BEFORE and AFTER.
