All workouts ever created have one thing in common: progressive overload
This is the gradual increase in weight, volume, intensity, frequency or time training in order to achieve a specific goal. Basically, the teeny tiny incremental improvements you make each time you step into the gym, lace up your trainers or enter the swimming pool.
Bicep curls, squats, marathon running, Olympic lifting and yoga are all designed to progressively adapt and improve something. This is because exercise, by its very nature, is an adaptive process. It’s the whole reason we do it.
If you’re not attempting to improve or progress in some way, it’s probably not training.
