how do i improve my 40 yard dash and vertical leap without strength training. technique is good.
i am on stretch program and tried plyometrics but they dont work
The best way to improve both of these exercises, WITHOUT true strength training would be weighted repetition.
This means, purchase some wrist/ankle weights, as well as a weighted vest. Gradually increase weight each week, and do many repetitions of both, with the weight attached. As time goes on, and you increase the weight further and further, as well as the repetitions.
Once you max out the weight, and the repetitions, shed all of the weight and attempt without any pre-exhaustion and without any weight. You will see a very noticeable improvement.
