First of all, I want to say that 178 60 kg is relatively thin, and 70 kg is almost the same ~ so I suggest you don't do aerobic activities often, because it will consume too much fat.

Have some bread, two eggs and a cup of soybean milk in the morning, because your digestion is not very good. Drinking milk in the morning is not recommended.

Then go hiking, return to normal study life, and start doing some muscle exercises at 3 pm.

If there is a gym near your home ~ you'd better go there and exercise all the equipment, and do it all once ~ Every day, make each equipment 12 as a group and do 3 groups, and you will feel like breaking the limit every time. Remember to keep doing it regardless of muscle pain. After you finish it, you will sweat and take a hot bath.

Conducive to the body fluid circulation. After the impurities are excreted, eat something to supplement a lot of nutrition ~ trotters, lamb chops, sheep whips, beef tendons and bullwhips are all good things to supplement physical strength and keep fit.

On the first day, you will fall asleep early, and wake up refreshed the next day, but your body will be very painful. Do not give up.

Next week, you will find that your gastric motility will be obviously improved, and your digestion and absorption ability will be better ~ ~ Of course, after more than one month, when you find that your physique has become strong, your weight will only increase slightly, and most of this increase is muscle ~
