I'm not in any way affiliated with this place, but I feel like I found such a gold mine that it would be wrong not to share. I was looking for a more affordable (and closer) option to the Michael Johnson Performance Center, and I came across Infinite Performance in McKinney. They do the same basic kinds of training that they do at MJPC, but it's just for youth (under age 18), and it's slightly cheaper. My dd has been doing one session per week, but based on the results I'm seeing, she's going to go 2x per week over the summer. After just five sessions, she's got better balance, she shaved time off her sprint, and she's harder to knock down when she's fouled. If you're looking for something like that, check them out. www.performtx.com
