A punching bag with a personality. Through AR glasses, glowing targets light up on the bag showing where to punch, it measures how hard you hit, and Bob trash-talks you to keep you moving.

One of our teammates had to sit out of Taekwondo Nationals due to a strain injury. The cause? A rushed 5-minute warm-up that just wasn’t enough. It was a harsh reminder: skimping on warm-ups (Even if it's boring) is a common mistake, but it leads to real consequences...injury, lost training time, and missed opportunities. It's also a great way for people to get active and stay healthy! We set out to turn that mundane yet critical step into something athletes actually look forward to: an interactive AR warm-up game. By combining guided drills, live feedback, and playful challenges, our system makes proper warm-ups engaging, adaptive, and fun-so athletes are ready to perform and stay safe.
