Skipping rope for 30-40 minutes can consume 300 kilocalories, while a bowl of white rice consumes about 2500 kilocalories. For every kilogram of fat lost, you need to burn about 7700 kilocalories. Skipping rope 1 hour can burn at least 1300 calories, which is equivalent to jogging for 3 hours and dancing for 2 hours, which is super slimming. I think you should stick to it.
