JinxxOr: Unfortunately, she wasn't hitting the bag correctly very often from what I could tell. Although the instructors are always telling her about her fists when she is practicing forms or punching into the air, no one was correcting her while she was hitting the vinyl bag yesterday. The tops of her feet and hands had splotchy red color to them that disappeared within a few hours, but they weren't burned. The abrasion on her foot was caused by the plastic base filled with water. The abrasion in itself was not a problem. The way it happened bothered me, though. It took only 10 minutes to redden her feet and for her to finally kick the base probably because she was getting tired of the punch-punch-kick-kick repetitions. Also, she said she was fine. I'm sure she was. However, I'm concerned about the long term consequences of potentially improper training techniques. At this point, I'm not completely sure what is reasonable and what is not. ZR440: They are encouraging her to kick higher into the air than her waist for the front, side, and round house. This generally isn't a problem for her unless she has to do several repetitions in a row. I haven't seen them say anything about height when she is working on a spinning back kick. She is also working on down blocks, middle punches, high punches, and high blocks (no sparring) as well as kee cho hyung il bu. I don't know why they put her on a bag. Her attention span is fine. She understands all about nit picking when it comes to form and technique on the piano, so such nit picking during TSD class for one hour wouldn't bother her at all. This Mommy will not renew the contract if they don't do everything possible to reduce the chances of serious injury. It looks like that maybe encouraging her to use an adult sized punching bag with a high base while using poor technique is not a necessary part of learning TSD at this time. I will probably try talking with the instructors about this. It's either that, look for another dojang, or quit altogether. ::sigh:: When I signed her up, I believed that TSD wouldn't be any more threat to her hands than riding a bike, skating, swimming, soccer, etc. From what I saw yesterday, I'm not so sure anymore. Thanks so much for your input.
