How to make latissimus dorsi look like Bruce Lee?

Strong and contoured latissimus dorsi can be obtained through the following cooperative training:

Second, bend down and hold the dumbbell horizontally and put it down;

Third, the tension spring is pulled on the chest and back.

The above three methods are combined with training, and the training time is kept for two hours every day, which is divided into 3~5 groups. It takes one month to get initial results, and three months to show the perfect latissimus dorsi.
