if this was the case, every NBA player would have a 48" vertical jump. Every 100m sprinter would be running sub 9.8 seconds.

Speed and power is entirely genetic. you're either fast or not. you can either jump high or you can't. you can improve it but only by slim margins.

Strength however, can be trained and improved greatly and well into middle age, which is why barbell training is so popular.

I develop the Official Starting Strength app.

Happy to answer any questions about the app or starting strength in general (although I'm not an SSC, I have done the seminar and been strength training for about 5 years).

Here's a bunch of free resources to help people get started:

Starting Strength youtube channel, check out the DVD section which has Rip coaching people through each lift. https://www.youtube.com/user/AasgaardCo

Get your form checked by a starting strength coach - http://startingstrength.com/resources/forum/forum171/ (read the sticky first about how to a useful video)

Starting Strength sub-reddit - Scott Hambrick (a starting strength coach) is active on there and will do form checks and give advice on general questions. https://www.reddit.com/r/StartingStrength/

Mostly in the US. There's coaches in Finland, Singapore, UK, Australia and Korea (and probably elsewhere). http://startingstrength.org/index.php/site/coaches
