Frequently asked questions
- Why is my weight going up but I look leaner?
- This is common when starting strength training. Muscle is denser than fat, so you may gain muscle weight while losing fat volume. Use body measurements and progress photos alongside the scale for a complete picture.
- How do I know if I am losing fat or muscle?
- Track body fat percentage, strength levels, and body measurements. If your lifts are maintained or increasing while losing weight, you are likely preserving muscle.
