I see...you have tough endurance but you fall down easily...Hmmm...Well, the first thing you have to do is have self confidence! Think in your mind that you have good balance! Then when they try to floor you then just try to keep your feet up. Next step if they keep on flooring you is to check if there's something wrong with your shoes! Shoes can be off a bit you know! I can't think of anything else.

Every night, practice bending you knees forward and pretend that you're sitting in a seat. Do that everyday and your balance should improve a bit.

hmm........good tips,ill try them
