My personal workout equipment: Dumbbell (Star Sports)

It's a dumbbell that my sibling used when they were exercising, and it was left unused for a while, but I'm using it now because I'm on a diet.

You can attach two 2-kilogram weights to a 1-kilogram bar, making it useful for arm exercises, lower body workouts, and arm exercises simultaneously. It's versatile in many ways, and you can also change the weights, which is great.
