Can you do a box jump? I certainly cannot. It’s a popular exercise among fitness enthusiasts. It takes incredible explosive power and lots of hours training the leg muscles to coordinate the movement of jumping vertically on to a raised platform. Seeing someone do this and understanding intellectually how it works are a good start, but doing a box jump requires practice. Lots and lots of practice. If you intend to perform a box jump in the long term, this also requires maintenance training, to keep the skills and muscle memory sharp. After not doing box jumps for a while, it might seem difficult to get right back into it, but after a while it all comes back.
I think it’s pretty obvious where I’m going with this.
