Yeah yeah, make fun, it's OK. I have no idea where else to ask this.
But seriously, all my size 30 pants don't fit anymore. I can only get into 31 and 32. My weight hasn't changed much (3lbs that usually fluctuate during the week).
Is it possible that muscle gains in abdomen and in lower back muscles could cause this or should I take a closer look at my diet?
Thin guys, your experience?
