Why, why is everyone against calves, if calves have nothing to do with jumping why does every vertical jump program use them. Why did my vertical go from 28 to 38 during a time when my training switched to a heavy concentration on calves, this was over 2 years by the way not a couple month bullshit story.
Where did you get the 1-3% of a jump comes from the calves, just random numbers?
Are we serious people, are we talking about calve raises considering all the running and jumps sprinters do each day. 28 to 38 thats very hard to believe, you should shoot my roomie your program, hes a football player and wants to increase his vertical jump.
