gaining speed and power

Question
im a 14yr old boy who wants to gain power and speed.i purchased the jumpsoles with proprioceptor, reaction ball, hypergravity weightbelt, all speed legs builder, thigh blasters at jumpusa.com (i would check it out).That stuff helps me to run faster but how would i use all that stuff in my schdule because i do squats,leg curls,leg extension,calf raises. Will all that stuff i bought strain my legs too much and do u think i should quit working my legs? because that stuff should help my legs get stronger or at leat keep my leg strength up. please answer those 2 questions   thanks!

Answer
Hi Blair
I have allread seen that site,and personally feel you should of saved your money.That said,your legs can only take so much,especially at 14 years old when your still growing.There is nothing wrong with working your legs,but any exercise you do should be in the proper sequence with proper rest and recovery.My recomendation is find a local trainer with experience and check his credentionals to help you get involved in a good long term program with your specific sport or sports in mind before you hurt your self.

The best to you Blair
