Increasing the intensity can do it. We basically get the water retention any time we increase the intensity or start something new. Basically, challenging yourself significantly!
4 lbs is still within normal fluctuation ranges anyway. Your weight isn't actually a static number. It's a vital sign, like our pulse or temperature. You can see an upward shift thanks to hormone levels, lack of sleep, sodium overdose... my weight can fluctuate as much as 9 lbs in a single 24 hour period!
In order to gain 4 lbs of FAT, you'd need to eat more than 14,000 calories OVER maintenance ranges... which it doesn't sound like you have.

Writer, mother, wife, and breadwinner. I love to run, but running doesn't love me, so I'm switching to my low-impact bike.
