I picked up a water bottle. Two bottles filled with water should be about 500ml, which is better than dumbbells. But once you lift it, you should always lift it, otherwise you will gain weight again and be fatter than before when you relax. Now I have a massage wheel, which massages my arms and legs. It's better to roll with that after applying slimming cream than to lift a barbell. At least that person should not grow muscles.
