You really lost weight. At the beginning, we should do small strength exercises and big strength assistance! If you exercise, it's best to go to the gym three times a week, the first time to the chest, the second time to the back, and the third time to the legs and shoulders! Do abdominal exercises every time you go! Specifically, I suggest that you just start practicing strong strength (chest, back, legs) with combined equipment to avoid pulling at first! Dumbbells can be used for small forces. When you start practicing, you can carry 60% of your maximum weight. Don't be greedy, set action standards! If you don't understand, you can ask the coach in the gym and the people who practice together!

If you eat, you'd better eat more cows, chickens and fish. There are some protein vegetables, such as beans! Don't drink and smoke too much, it's not good for your health! Eat four meals a day. You can cooperate with protein powder at first! Rule of life, don't stay up late!

My personal height 177, weight 74kg. I have been in the gym for 3 years! Finally, I wish you success!
