#1 - Pictures tell a better story than the scale. Before reading any further, which pic do you think I weight the least in??? Got it! Feel free to comment below with what you thought. The answer the middle one! Although I'm more lean in #1 and #3 I dropped to my all time low weight after completing Body Beast and before starting Hammer and Chisel. I had stopped working out consistently and my eating was just... meh.
I weigh 8 lbs more in the first pic than the middle one. Yeah I lost 8 lbs by not working out as much. That's not a justification to not work out, just so you know. I lost muscle mass and I gained fat. Not a good combo. The last pic I'm up 2 lbs since starting Hammer and Chisel. The cool thing is I can just feel my body changing. Clothes fit better, my shoulders feel broader and pulled back, I just feel strong!
#2 - A backslide or a plateau doesn't mean the end of the world. Think about what helped you with your initial progress and go back to that. For me that meant following a program strictly. I just do better when I have a calendar to follow. If I don't, it leaves too much up to chance. For you it might mean being held accountable or meal planning, whatever it is, return to the process and trust it.
#3 - Muscle burns fat! I posted this pic in a giant accountability group I'm a part of and one guy was disappointed that he didn't have any abs showing yet from the workout. He even posted a pic of his current self and it showed him to be on the skinny side but a little bit on the "soft" side. Or some would call it skinny fat! If you want to burn through layers of fat, work on building the muscles underneath that fat first.
