For me I Crossfit 6 days a week, there is almost ALWAYS some form of lifting involved. I weigh daily, and truth be told I rarely see my lifting effect the scale. If there is water weight there it's well, always there cause I lift every day. Even if there is a jump from water weight, I can't really pin point when it will happen. More typically it will happen on a rest day, but that's just my body personally.
I could be totally off base, but that's just my two cents from personal experience!
Odd, because everytime I weight lift the numbers are insane! Way larger the next day. Whenever i do cardio though, its not really affected at all.
