Learn Spanish (Latin America): ¿Sigues estirando las piernas para evitar una lesión? - Are you still stretching your legs to avoid an injury?

To say you "keep doing" or "are still doing" something in Spanish, you use the verb seguir (to continue or follow) plus the gerund (the -ando or -iendo form of a verb). Here, sigues is the "you" form of seguir, and estirando is the gerund of estirar (to stretch). Together, they mean "you are still stretching" or "you keep stretching".

Why does it say las piernas (the legs) instead of tus piernas (your legs)?

In Spanish, when you talk about body parts, you almost always use the definite article (el, la, los, las) rather than a possessive word like mi or tu. Because the context makes it clear whose legs are being stretched, las piernas naturally translates to "your legs" in English.

Why is evitar in the infinitive (unconjugated) form here?

It follows the word para (in order to). In Spanish, whenever a verb directly follows a preposition like para, por, de, or en, it must stay in its infinitive form. So, para evitar means "in order to avoid".
