This puts strain on the muscles in the front of your leg, which unfortunately are not strong enough to resist the pulling. Ouch.由于你连在脚踵上的小腿腓肠肌紧张而无法伸展,引起脚趾被拉低,这让你小腿正面的肌肉受到压力,而你小腿正面肌肉还无法对抗这种拉力,好疼!
It's your body's way of telling you something is wrong. Don't involve yourself in an activity that puts strain on joints that are already painful or stiff.那是你自己的身体在告诉你有什么不对劲的方式,不要沉迷于易导致关节疼痛或僵硬的的活动。
