Nike would be one of my favourite brands. I was very sporty a few years ago and played Basketball regulary at a high level. I always bought Nike shoes for comfort and found the clothes fit well and last longer .I still use Nike when I go to the Gym and causual tops and pants look great.....be legendary
Be careful who you take your advice from. Just because someone else tells you something is impossible doesn't make it so. What do you want to achieve? Find people who are doing it and learn from them. If you can't find anyone I guess you'll have to be the first person to do it.
Mind over body. Your stomach grumbles when it is hungry your mind tells it not to eat. Your muscles ache when you are tired and burned out. Your mind chooses to press on. Your eyes see the result of your minds choosing. Your mouth begins to smile.
