I remember once going to the gym and seeing a fitness instructor. After he took off his clothes, the shark line on his body was striking. Then many young ladies around me really stopped running and looked at the coach. At that time, many people screamed at the scene, and many boys went to ask the coach how he was practicing. I silently hid in the corner and witnessed all this.
It can be seen that shark line is really attractive. I guess the fitness instructor may have added WeChat by many people, and can start classes, but this is the result of people's efforts. Fitness whites like us, when they saw this great god, turned to have a look. This figure is estimated to have nothing to do with me in my life. I can only look forward to finding a boyfriend with a shark line, but this should be considered a rare species.
Of course, the above is purely a joke. If you want to practice shark line, you can consider trying the following actions. First of all, you should hang down your legs, roll your abdomen with the weight of the stretcher, bend your knees, hold your legs with your arms and do sit-ups. There are other daily strength training. Every time you do it, you must ensure the accuracy of the action, not just the quantity, but the standard is the most important. Finally, we must persist.
