Non-scale ways to track your weight loss

Before I started training with Sham a couple of months ago when I would shower I'd bring my beach towel sized towel with me. The regular sized towels hardly fit around my body


Now, the regular towels are fitting around my waist and body perfectly!With the exception of a small gap around my thighs. I decided a while ago that the towel would be one way I'd gauge my progress. Rather than obsessing over what the numbers on the scale will be, I find that keeping other measures, like my towel method, is less punishing and keeps me feeling like I'm successful in my shape-up goals even if it's not quantifiable in pounds.

What non-scale ways do you use to measure your progress?
