When it comes to fitness, progress can be measured in various ways beyond just the number on the scale. Non-scale victories are important indicators of improved health and fitness levels. These victories can include improvements in strength, endurance, flexibility, and overall well-being.

For example, being able to lift heavier weights, run longer distances, or perform advanced yoga poses are all non-scale victories that demonstrate progress in fitness. Additionally, improvements in energy levels, mood, and sleep quality are also important non-scale victories that reflect positive changes in overall health.
