It is better to have a treadmill. Jogging slowly increases time. Running is slimming, and persistence is very important. After running, you can dumbbell after a short rest. Pay attention to practice with your hands together and start practicing lifting. You can practice sitting or standing. At first, you can use 15 as a group, three groups at a time. Later strength goes up and then five plus one. With arm strength, the chest muscles are relaxed. The simplest thing is push-ups and group exercises. Finally, the abdominal muscles are hard, so do sit-ups. As long as you can persist in not being lazy, the effect will be obvious for half a month ~ it is enough not to go to the gym at all.
