jump soles

[beefybull]

reasons? - to blow your achilles tendon that's why

calves are barely 10% of a jump as well anyway.

They are good for walkinga round it to make your calves bigger, and for that they work well .

I've heard calves are around 30%, but I'm not sure about that figure either. Anyone have any links with info?

supertraining had an article on this a while back. Basically as a starter it said try jumping with just your calves and see how high you get.

I did the full jumpsoles program 2 years ago. I gave it my all and got little improvement. I think like ccj the jumpsoles themselves might not even help or may make things worse. In most cases for bball players driving up the squat will have a much greater effect. (if you squat over double bodyweight, then just focus on developing speed strength while maintaining your maximal strength)
