Learning yoga and learning weight training

So my take here is when you start to go to the gym and the instructor is instructing you in different weight training exercises, in one time, two times in a month or in a few years you won't develop the feel of the weight training exercises for different body parts, muscles. So just imagine, if somebody is teaching you yoga, it will take you many decades to actually develop the feel. And to go deep into meditation and hope for attaining samadhi. So, thing is, keep your mind open, full concentration, full focus and try to understand what you are being taught. Think on that.
