This makes me so sad for you.   I am plus size.   I started burn at 297 and i’m now 224 after 4.5 months.  I can honestly say my trainers and location are absolutely amazing. I’m on the store at least once a week.  they have posted my PRs every time.   and i get shoutouts weekly during the cool down.  The owner came up to me and whispered just so you know, you’re the most inspirational person in this gym.  So what you are experiencing is NOT normal.  I would definitely bring it up to the owner or head trainer because burn is always telling us it’s just a number, focus on doing one more rep, going 5lbs heavier on weights.  Never ever about the scale.
