I stopped weight training a few years ago to get lean and become a better roadie.
After heaps of kilometres and weight loss I was no faster than before.
SO, I decided to pump my sprinters body back up...
After only about 10 weeks I've lost fat (I can nearly see my abs now) and ballooned from 92 kilograms up to 98!!!! Holy cow, I couldn't believe it!!!!
Thats at least 6 kilo's of muscle in 10 weeks. I wish I could have managed that in my skinny teens!! It seems almost impossible!! But I'm pretty happy with it. And yes, I'm immediately faster... Especially on the track
