I stuffed a bag with random clothes and blankets and throw it at the wall / at my wife / at the sky. It’s about 5kg / 11lb. Not as good as an actual medicine ball, but way cooler than plyo push ups.
You could also just jump instead of throwing. Throws and jumps are full body movements.
The whole point of the jumps, throws, hill sprints, prowler, etc. is that Jim wants us to think “athletic and awesome” or “all around strength”, and not just “unfit blob that can walk up to a monolift” (hopefully with no stairs along the way). His big love was/is football, and those guys are strong in all areas. Few things are more awesome than someone who can squat massive weight, sprint crazy fast, jump high, play with their kids all day without breaking a sweat, etc. You paint your own picture of awesome, and ask yourself if plyo pushups serve that goal. To me, plyo/explosive pushups just seem like something people mess around with when they have no goals/vision. Or something PTs prescribe their clients to look smart/scientific.
