power application is well in excess of what is required to lift the light suitcase and it flies off the floor. Rock climbing Complex training may be utilised by rock climbers in order to develop their ability to apply power quickly either in terms of dynamic movement or in the securing of holds. A complex training programme for rock climbers may be very sports specific. Notably, the first resistance exercise is often, but not necessarily, replaced with an isometric exercise or hold, before being followed by a dynamic power exercise. For instance, weighted dead hangs followed by doubles on the campus board. Whilst this is a sports specific variation, the underlying ambition is the same as with other forms of complex training; to maximally stimulate the nervous system whilst increasingly recruiting fast-twitch muscle fibres in order to improve the ability to apply power.
