It all started with ‘socceraerobics’, developed by René Wormhoudt between 1992 and 1997 and introduced in the youth department of AFC Ajax. Co Adriaanse was head of the youth department at that time. Socceraerobics was a versatile movement programme, in which moving to music was included from the moment the growth spurt started in young athletes. The programme consisted of coordinative movements, which were new and different, but also had the capacity to transfer to football performance, through BMS. Within the programme, attention was paid to elements like rhythm, spatial orientation, balance, posture and non-preferred rotational patterns. This was all packaged into extensive choreographies of eight blocks and had names like the China 1, Tibet 2 and Nepal 3.
