And remember the economy puts strain on the recipients too, Bernardo said.

别忘了，接受者也要承受经济压力。

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。
