Let me answer your question first.

1: Strength training is only three or four times a week, which has better time effect on muscle recovery than daily training ~

2. Because of reducing fat, try to be aerobic every day, not 4 to 6 times a week. In fact, aerobic exercise is not the best way to reduce fat. Let's talk about it later ~

Running and swimming can be done on the same day. Your coach is right, but the explanation is a bit inaccurate.

Popularize the knowledge of fat reduction: fat reduction, aerobic and anaerobic. The difference between the three is that in terms of heart rate, these three heart rates increase in turn.

In fact, it takes at least 40 minutes to lose weight and the heart rate. Generally, the heart rate is 60% of your maximum heart rate, so running and cycling have no good weight loss effect, or it depends on the heart rate ~

About 20 years old is the heart rate 120. In fact, brisk walking can also reach this heart rate, and jogging is not easy to persist. However, your jogging speed is slow, but I personally feel that walking fast is more comfortable and doesn't hurt my knee so much. You said that losing weight doesn't have to hurt your health, right?

Take the heart rate as an example, because you can't swim at such a high heart rate, you will suffocate when swimming. Therefore, the effect of swimming on reducing fat is not good, but running without weight control is easy to thicken the calf, and swimming has no stimulation to the calf muscles.

So remember time+heart rate, eat low in calories, but not on a diet! Basic fat reduction is no problem!

Doing anaerobic training first and then aerobic exercise is also conducive to reducing fat, so that the body can enter the fat-reducing mode faster ~

I wrote a lot, thank you for your patience ~

I am also a chubby person, I have studied this ~ I hope it will help you ~
