Relaxation In this lesson attention is paid to stretching and core stability in combination with breathing. You work on mobility, agility and strength and learn to stand firm and stable. In this lesson you do the exercises in sync with your breathing, which causes a redistribution of both physical and mental energy which goes hand in hand. Regular performance of these exercises improves your immune system and has a positive impact on your overall health. The training takes place on squash court 1 and is accessible to anyone with a valid OlymPas. What to bring Please bring a towel (obligated).
