What you can do inside The SIX: * Complete structured fitness tests that cover strength, power, speed, capacity, endurance, and conditioning * Get your personal SIX rating based on your results * Track your progress over time as your rating increases * Create head to head comparisons with friends to see who wins, loses, or ties across each of The SIX * Record in-app video of your attempts so others can watch your lifts and efforts * Learn correct technique from Gymshark Lifting Club coaches with built-in movement guides and videos * Share achievement stickers and rating cards straight to Instagram and other social channels for social proof * Build social currency around your effort, not just your appearance * Compete on leaderboards and see where you stand The SIX creates a democratised rating for fitness. It gives every lifter and gym goer one clear number that reflects real performance, not opinion. Your training already matters. Now it counts. What is your SIX?
