Dear Marcelo Silva

in your situation the barbell squat jumps could be substituted by Plyo swing machine, but in my opinion the barbell squat jumps is more effective that Plyo swing machine to develop the explosive strength in the push up movement.

I know that soccer players don’t like weight training but they really need it.

In Italy has been found a compromise: the soccer players use the barbell squat jumps “in castello” (Technogym Multipower or Smith Machine).

The hurdle rebound jumps is e very good exercise but it is finalized more to develop the speed strength. You can use this exercise logging the total execution time of 7-10 hurdles jumps.

I must suggest you to use this exercises with hurdles more low  and “soft” that I saw in your video, because this exercise is very dangerous: I was witness of very bad accidents during its executions.
