You can add plyos if you want, but I don't think you will gain much benefit. Much better in my opinion to use that same amount of time either recovering from a previous workout, eating or getting stronger. People should realise that there is only so much that they can do in a fixed amount of time. Keep it simple. Get strong. Carry on balling. Your vert will increase.
