Hey there! Thanks for checking out this long post! I am interested in purchasing a instructional Tai Chi video/DVD. My brother has one and I find it a good exercise for balance and developing a "core" strength. I was thinking of getting my own to do at home. I know taking a class would be better. But for possible lack of time and funds I am opting for the video. I did Taekwondo for a year, it was like 7 years ago but I earned the orange belt. I also tend to work out regularly at school, mostly weight lifting. I am a bit overweight, 5'9" and 220lbs.,(but don't look it! ) and don't consider myself to have a good "core" strength. For example doing twenty push-ups makes me feel winded and I have never been able to do a pull-up, lol. However, I am very flexible/agile for my size and have a good amount of stamina/determination when it comes to these things. At the gym I don't do too bad with my weight lifting. My legs are especially strong and once I did 2 sets of 10 reps on the leg press with 500+lbs, maxing out the machine. I am also starting to do swim exercises and probably going to join a local Wu Shu club at school. Hope this isn't too much info. Let me know what you think.
