Body Recomp Radar
Scale stuck but waist shrinking? Decode simultaneous fat loss and muscle gain.
When the scale barely moves for weeks, are you stuck in a plateau — or losing fat while gaining lean muscle? Compare your start vs. current weight and waist to decode body recomposition.

📏 Practical toolkit tip — Self-Tightening Body Tape Measure (MyoTape style, ~$7)
Why it helps: Locks around your waist, hips, or neck with consistent spring tension so you don’t accidentally pull tighter from week to week.
Pro tip: Always measure on bare skin after a normal, relaxed exhale first thing in the morning.
