This document discusses three social media platforms - YouTube, Tumblr, and Vine - and how a leisure centre can use each one. YouTube allows uploading fitness and nutrition videos which can attract new members. Tumblr is suitable for posting images and videos about classes and workouts. Vine is ideal for creating quick fitness tutorials and promoting facilities in 6 seconds or less. However, producing videos requires staff costs and there are copyright issues with YouTube. Tumblr has spam and security problems while Vine's 6 second limit is restrictive.
