YDY is an exciting fitness video game that offers a unique racing adventure, powered by your heart rate. The higher your heart rate, the faster your character goes, so get ready for a heart-pumping experience!

But that's not all - YDY releases new races every week, which vary in length and structure, and can be either endurance or high-intensity interval training. You can compete against others while reaching your fitness goals.

With multiple different maps to race on, YDY offers endless hours of entertainment. You can use powerups called Treats that allow you to shoot fireballs, get a speed boost, and even become invincible.

Whether you're a fitness enthusiast or just looking for a fun way to stay active, YDY is the perfect game for you. So, join now and experience the thrill of racing while achieving your fitness goals.

The Higher Your Heart Rate, The Faster You Go

The faster your heart rate, the faster you'll power your Hyperpack to go - the vehicle you use in the game. Be careful not to push yourself too hard - if your heart rate goes above 90% of its maximum, it will overload the Hyperpack and slow you down. It's important to find the sweet spot where you're pushing yourself to your limit, but still able to maintain your pace and stay in the lead. Get ready to race, have fun, and hit your fitness goals with YDY!

Gain an Edge to Win with Power-Ups!

Treats are power-ups that appear scattered throughout the map. The speed boost treat can increase your power and speed for a short duration. The fireball treat will temporarily stun your opponent in front of you. For a longer duration of speed and invincibility from fireballs, the lightning treat is the way to go. These power ups add an extra element of fun to the game, giving players a chance to gain an edge and catch up with their opponents. Make sure to beat your opponent to the treats to reap the rewards.

AI Competition Adapts To Your Abilities

Our fitness game is powered by AI, which adapts to your specific fitness ability. As you improve over time, the AI adjusts to keep pushing you to your limits. You'll never get bored with the same old races, as the AI competition ensures that every race is different and challenging. Whether you're just starting your fitness journey or are a seasoned athlete, YDY's AI competition will keep you on your toes and help you achieve your fitness goals.
