Hey Balsa! I typically program general dynamic warm-ups like jogs/backpedals, shuffles, karaokes, and walking lunges for a few minutes before more intense plyos, but plyo's themselves can also be fantastic warm ups because they're essentially ballistic stretches with load. Good to get them into deeper ranges of motion with less impact force before demanding more. Skip variations, multidirectional light pogos, something like split jumps with depth, and then transitioning into more intense and explosive plyos like broad jumps, vert jumps, single-leg bounds, and triple jumps would be a good way to go about it. That way, you're getting a lot of variety and not taking too much time on warm-up + plyos. Love Matthew's advice here with the low-stakes obstacle courses! Especially fun for younger athletes.
