Functional movements are simply natural movements that have an equivalent in everyday life.
For example, you also make a knee bend when you get up from a chair or deadlifts are exactly the same as lifting shopping bags. Functional movements are always compound exercises (compound or multi-joint). This means that several joints and muscles are always used at the same time. That’s the complete opposite of working out on machines in a fitness studio. There, muscles are often trained separately and usually also while sitting.
Functional movements are really the new trend in the fitness industry, but not everything that is sold as functional movement there is actually it. In my opinion, functional movements should complete a task or have a similar movement in everyday life.
Another important feature of functional training is that you move large loads quickly compared to your body when it comes to weight and distance.
