racezone3.co.uk £12 A sponge rectangle that floats. Hold it out in front of you and kick up and down your lane. Benefits: A kick board isolates the kick part of front crawl swimming. It helps you focus on kicking efficiently from the hips (not the knees) without getting side-tracked by having to move your arms and upper body. Tip: You don’t always need a kick float to practise your kicking. Try kicking on your side with one arm out in front, rotating your head to breathe.
