So my daughter went up another age level in supine core, prone core, upper body, balance beam and brachiation by one year. So in two weeks her strength has improved by two years. I was talking to her about brachiation and she said that she was only able to hold on to the monkey bars to the count of four. I thought she was able to go across at least half way. It is supposed to be 77 degrees on Saturday, I'm going to take her to the park and see for myself.
My daughter has "With Wolves and Whales" which is located at the bottom of http://www.i-waveonline.com/iwavesamples.htm in case you want to hear for yourself some of the samples she listens to everyday.
