Small update. So far, I am making significant progress with my kicks and punches. The bag helps a lot on my off-days, as it gives me something to focus on. Instructor says that I need to work on my speed for the kicks and precision, because I mostly go out of target, with my back and turning-back kicks. He also told me to work on my power for my punches and keeps telling me not to tense my shoulders when I prepare to deliver them. Will doing pushups as an exercise help me develop the power in my punches (apart from the proper technique) or will I be better off doing time with the bag?
We will also be sparring soon and we are being prepared for it. 2 questions though: 1. There is a substitute instructor who will be with us for 3 months because the junior TKD instructor had to go on leave because his wife is giving birth. Anyway, this new instructor teaches a bit differently from the senior instructor. For one, the senior instructor always tells us to keep our guard up when sparring and doesn't hesistate to hit us on the temple with the kickpad when our guard is down. The sub teaches us to relax our guard and just keep it at the sides, but ready. He says it is to conserve energy. Is it ok to tell him that I prefer to keep my guard up or is it ok to bring this up with the senior instructor (if so, how do I do it without making him look bad)?
2. As soon as we are comfortable sparring with one another, the senior instructor says that he will bring 1 or 2 of his black belt students to go at it with us. As a white belt going on yellow, anything I should look out for? And is it ok to go all-out?
