The Dumbbell Sports Drink designed by Jin Le. The bttles can be filled with the water or electrolyte infused sport's drink, each bottle eight scant 0.5 kg. After you drink it up, you can also fill it with water or sand and use it as a dumbbell.
Even though it might not be the perfect weight for a professional workout, it can be a fun way to keep yourself in shape around the office. The best thing is if it gets too heavy on your muscles, you can always make it lighter by taking a sip.
