So: 1, insist on push-ups, squatting with both hands raised, lying flat with your head held, etc. But persistence is very important, otherwise (especially young people) will easily rebound.
Also, everyone's physique is affected by heredity, so don't be a toddler, as long as you can keep exercising and reduce the intake of fat and high calories appropriately, even if your weight is higher than your peers.
I sincerely wish you good health.
